“…Diffusion of anions into the interlayer is the ratedetermining step in the reaction; therefore, the exchange reaction is performed by alternating stirring the ZLH precursor in an excess solution. Ultrasound methods are encouraged to speed up the exchange reaction [28,38,[40][41][42]. Based on Hashim et al [33], ZLH nanocomposite prepared by the co-precipitation method showed less thermal stability and crystallinity than ZLH nanocomposite synthesis using the ion exchange method.…”

“…Special attention has also been focused on controlled-release formulations of pesticides using layered materials in agriculture. There are many new nanocomposites involving pesticides that have been intercalated into interlayer of ZLH such as cetyltrimethylammonium bromide [125], chloroacetic acid [33], valeric acid [47], propoxur [41], isoprocarb [126], thiacloprid [28], 2-methyl-4-chlorophenoxyacetic acid [34], 2-(2,4-dichlorophenoxy) butyric acid [55], and 4-chlorophenoxyacetic acid [127]. The successful intercalation process of pesticides into the interlayer of ZLH was due to positively charged ZLH layers that promote the attraction force between the guest anion pesticides and the host.…”

Zinc Layered hydroxide (ZLH) is a layered material easily synthesized with a structure identical to brucite-like material. Due to the exchangeable anions in the interlayer compensating for the positive charge of a brucite-type layer, ZLH provides a wide application in many fields. This review focuses on the properties and method of synthesis of ZLH by giving an overview of intercalated guest anion in the interlayer of ZLH. The further discussion involved the application of intercalated guest anion in zinc layered hydroxide layer and its properties as a sensitizer, controlled release biomedical, and agriculture to provide the scientific community for research and development by giving current findings. This brief review also presents the success of anion intercalation for controlled release along with the kinetic model involved, which increases the bioavailability and effectiveness of the nanocomposite on its target. It shows the development of research on ZLH nanocomposites toward the sustainability of human life and the environment. This study implies that it is a source of knowledge for researchers about zinc-layered hydroxide materials involving synthesis methods and their application to produce more beneficial nanomaterials.

“…The first step of thermal decomposition with minor weight loss was 3.75% at 125 °C for ZLN and 2.5% at 92 °C from ZLP. This was due to the elimination of water molecules that exist in the interlayer space (Muda et al, 2018). This was followed by two weight losses at 150 °C (5.00%) and 175 °C (3.75%) in ZLN while ZLP recorded a weight loss of 3.00% at 163 °C.…”

The loss of nutrients from conventional fertilisers is often encountered by the agricultural industry. Slow-release fertilisers by nanotechnology application can maintain nutrient availability for effective plantgrowth. Zinc-layered hydroxide nanohybrids have been little explored as controlled release systems offunctional anions, unlike the Layered Double Hydroxides (LDH) that belong to the same family ofanionic clays. The objective of the study was to investigate the effectiveness of zinc-layered hydroxidenanohybrid containing plant nutrient anions as a controlled-release formulation. Two nano-deliverymaterials namely zinc-layered hydroxide nitrate (ZLN) and zinc-layered hydroxide phosphate (ZLP) weresuccessfully synthesised through the co-precipitation and anion exchange methods. The PXRD patterns ofthe resulting nanohybrids, ZLN and ZLP recorded basal spacing of 9.57 and 6.78Å, respectively, at alower 2 angles range of 0-60 o . FTIR analyses confirmed the formation of host-guest nanohybrid whichcomprised the characteristic bands of nitrate and phosphate. Thermogravimetric analyses showed thethermal stability of the nanohybrid obtained where the capability of the host material to function as acontrolled release agent was determined through a controlled release study. Controlled release of plantnutrient sources, nitrate and phosphate from their respective nanohybrids were evaluated using variousrelease medium solutions. The accumulated release of guest anion from interlayer zinc layered hydroxide(ZLH) nanohybrid into pH 4 solution was observed to be faster than pH 6.5. A higher concentration ofsodium carbonate solution showed an increase in the percentage release for both nitrate and phosphateanions into the release medium. A plant growth trial using Kelempayan (Neolamarckia cadamba)seedlings showed that treatment with ZLN and ZLP recorded the highest biomass weight compared toapplication with commercial fertiliser and raw chemicals. The content of N, P and Zn in Kelempayanleaves showed the highest readings for similar treatment. The study found that ZLH has acted as a goodhost for inorganic plant nutrients with slow-release properties and thus has improved the growthperformance of Kelempayan seedlings with better nutrient uptake.

“…Zn-LH is the most common one used to host various AI guests for the synthesis of nanopesticides that can be found in the literature, as shown in Table 4 . For example, isoprocarb and carbamate were separately intercalated into the Zn-LH for the formation of their nanoinsecticides, resulting in better thermal stability and environmental friendliness of the AI compared with their counterparts [ 61 , 62 ].…”

The rapid growth in the human population has triggered increased demand for food supply, and in turn has prompted a higher amount of agrochemical usage to meet the gaps between food production and consumption. The problem with conventional agro-nanochemicals is the reduced effectiveness of the active ingredient in reaching the target, along with leaching, evaporation, etc., which ultimately affect the environment and life, including humans. Fortunately, nanotechnology platforms offer a new life for conventional pesticides, which improves bioavailability through different kinetics, mechanisms and pathways on their target organisms, thus enabling them to suitably bypass biological and other unwanted resistances and therefore increase their efficacy. This review is intended to serve the scientific community for research, development and innovation (RDI) purposes, by providing an overview on the current status of the host–guest supramolecular chemistry of nanopesticides, focusing on only the two-dimensional (2D), brucite-like inorganic layered hydroxides, layered hydroxide salts and layered double hydroxides as the functional nanocarriers or as the hosts in smart nanodelivery systems of pesticides for plant protection. Zinc layered hydroxides and zinc/aluminum-layered double hydroxides were found to be the most popular choices of hosts, presumably due to their relative ease to prepare and cheap cost. Other hosts including Mg/Al-, Co/Cr-, Mg/Fe-, Mg/Al/Fe-, Zn/Cr- and Zn/Cu-LDHs were also used. This review also covers various pesticides which were used as the guest active agents using supramolecular host–guest chemistry to combat various pests for plant protection. This looks towards a new generation of agrochemicals, “agro-nanochemicals”, which are more effective, and friendly to life, humans and the environment.
