“…[13] This applies also for homogeneous catalysts, which can exhibit high mass activity, but their subsequent recycling is tedious and very often even not possible, for example, in catalytic oligomerization reactions. [111] Likewise to the synthesis of silver NPs for antimicrobial activity, sensors, [104] and catalysis, [112] lignin has been used as a complexing, reducing, and capping agent for the synthesis and stabilization of gold, palladium, ruthenium, and rhenium [113][114][115][116][117] NPs. Lignin-capped palladium NPs were used to catalyze cross-coupling reactions in water with good selectivities, indicating that the presence of lignin does not impede catalytic activity of metal NPs.…”

“…[116] The ability of lignin to stabilize metal NP dispersions is related to the polyelectrolyte layer formed on the surface of metal NPs. [117,118] However, it is not clear which are the most suitable charged groups, net surface charge, and molecular weight distribution of lignin in this application.…”

Lignin is one the most fascinating natural polymers due to its complex aromatic‐aliphatic structure. Phenolic hydroxyl and carboxyl groups along with other functional groups provide technical lignins with reactivity and amphiphilic character. Many different lignins have been used as functional agents to facilitate the synthesis and stabilization of inorganic materials. Herein, the use of lignin in the synthesis and chemistry of inorganic materials in selected applications with relevance to sustainable energy and environmental fields is reviewed. In essence, the combination of lignin and inorganic materials creates an interface between soft and hard materials. In many cases it is either this interface or the external lignin surface that provides functionality to the hybrid and composite materials. This Minireview closes with an overview on future directions for this research field that bridges inorganic and lignin materials for a more sustainable future.

A very important topic in present-day research is the depolymerization of lignin, meaning the multi-parametric decomposition of the biopolymer into low-molecular-weight products (monomers) by breaking of the intermolecular bonds. Depolymerization can occur under many different factors, such as high temperature or catalysts, which determine the mechanism of disintegration. In the case of lignin, this process is carried out in order to obtain many valuable low-molecular-weight compounds. It is becoming more and more popular as a result of the use of ionic liquids, but methods using alkaline, acidic, and metallic catalysts, as well as pyrolysis and supercritical fluids, are also known. All of these methods will be described in detail in this chapter.

“…If the M NPs are irradiated by light, strong optical absorption and/or scattering phenomenon will happen forcefully relied on their size, morphology, and dielectric environment, which is recognized as localized surface plasmon resonance (LSPR) [9][10][11]. Consequently, M NPs show the intense colours owing to the collective oscillation of conduction electrons upon interaction with light and this particular property has been widely developed in catalysis, optoelectronics, sensing, and surface-enhanced Raman scattering (SERS) [12][13][14][15][16]. Further declining the size of metal nanomaterials into around 0.1-2 nm, M NPs turn into metal nanocluster (M NC) region [17].…”

Noble metal nanoclusters (M NCs), defined as an aggregation of a few to tens of atoms, are considered a borderline between atoms and metal nanoparticles (M NPs), which tends to exhibit molecule-like behaviours such as discrete electronic state and size-dependent fluorescence. In the past decades, gold and silver nanoclusters (Au NCs and Ag NCs) have been massively explored and utilized in the field of industrial catalysis, optoelectronic devices, biological imaging, environmental detection, clinical diagnoses, and treatment. The analogue of Au and Ag NCs and platinum nanoclusters (Pt NCs), especially their biological applications, is relatively and rarely discussed. This review firstly investigates the synthetic methodology of Pt NCs including template-assisted and template-free approaches and then introduces their unique optical, catalytic, and thermal properties. Particular importance here is the biological applications of Pt NCs such as the bioimaging of various cells as a preferred fluorophore in contrast to traditional fluorescent markers (e.g., organic dye, semiconductor quantum dots, and fluorescent proteins), the usage of Pt NCs-based antitumour drugs as a new class chemotherapeutics for malignant tumour therapy, and the utilization of antibacteria as an alternative of Ag-based antibacterial agent. On the whole, the development of Pt NCs has already gained delectable progress; however, the study of ultrafine Pt NCs is at the beginning stage and there are still plenty of challenges like synthesis of near-infrared (NIR) fluorescent Pt NCs, the explicit signal pathway of cell apoptosis, and attempt in diverse biological applications that need to be urgently tackled in future.
