“…For the removals of cadmium (Cd 2+ ), arsenic (As 5+ ), chromium (Cr 2+ ), iron (Fe 3+ ), and manganese (Mn 2+ ) ions in wastewater, zeolite Na-X modified with Fe 3 O 4 , zeolite W modified with iron-zirconium, natural zeolite modified with Fe 3 O 4 , and zeolite 4A modified with titanium dioxide have been applied [25][26][27][28][29] . For the removal of lead (Pb 2+ ) ion in an aqueous solution, many studies have used commercial zeolite modified with CuO and Fe 3 O 4 , natural zeolite modified with MnO 2 and iron oxide, and zeolite Na-X modified with Fe 3 O 4 25,[30][31][32] . However, no one added iron(III) oxide-hydroxide along with changing material form to improve zeolite A adsorbent for eliminating lead contamination in an aqueous solution.…”

The discharging of lead-contaminated wastewater is a concern because of its toxicity to living organisms and water quality resulting in dangerous water consumption, so it is highly recommended to remove lead from wastewater to be below water quality standards for a safe environment. Zeolite A sugarcane bagasse fly ash powder (ZB), zeolite A sugarcane bagasse fly ash powder mixed iron(III) oxide-hydroxide (ZBF), zeolite A sugarcane bagasse fly ash beads (ZBB), zeolite A sugarcane bagasse fly ash powder mixed iron(III) oxide-hydroxide beads (ZBFB), and zeolite A sugarcane bagasse fly ash beads coated iron(III) oxide-hydroxide (ZBBF) were synthesized and characterized in various techniques. Their lead removal efficiencies were investigated by batch experiments, adsorption isotherms, and kinetics. The specific surface area, pore volume, and pore size of ZB were close values to zeolite A standard (STD), and ZBF had the highest specific surface area and the smallest pore size than others. ZB and ZBF demonstrated crystalline phases whereas ZBB, ZBFB, and ZBBF were amorphous phases. The surface morphology of ZB was a cubic shape similar to STD. ZBF demonstrated an agglomerated formation of ZB and iron(III) oxide-hydroxide whereas ZBFB and ZBBF had sphere shapes with coarse surfaces. Si, Al, O, Fe, Na, Ca, O–H, (Si, Al)–O, H2O, and D4R were detected in all materials. The surface charges of all zeolite A materials had negatively charged at all pH values, and their surfaces increased more negatively charged with increasing pH value which pH 5 illustrated as the highest negatively charged in all materials. Their lead removal efficiencies were higher than 82%. Langmuir isotherm and pseudo-second-order kinetic models were well explained for their adsorption patterns and mechanisms. Finally, ZBBF is a good offer for applying in industrial wastewater treatment systems because of its easy operation and saving costs than ZBF.

“…Usually, zeolites are crystalline and mostly microporous, but they can also be meso-or even microporous, for instance, due to modifications [17,36]. Some of the characteristic features of zeolites and their analogues are their high surface area (~1000 m 2 /g), highly ordered micropore channel system with uniform pore sizes and shapes [60,162], and the presence of charges and ions at well-defined sites in the framework.…”

“…An aim in doing so is to prevent catalyst/material aggregation, and the associated loss of (catalytic) function [40]. Different architectures have been reported, including simply containing the metal catalysts in the mesoporous (nano)zeolites [16,17] or as layered zeolites [99]. For interest in zeolites and their catalytic activity, readers are referred to available reviews on the topic such as Xu et al's [40].…”

“…Incorporating porosity into nanomaterials then presents exciting possibilities entailing further exploration of their physics and potential applications. Specifically focusing on porous inorganic nanomaterials and their hybrids, new materials have been developed, including porous metal nanostructures, porous oxide nanomaterials, porous carbon nanomaterials, nano-sized metal-organic frameworks (MOFs), and nano-zeolites [10,[13][14][15][16][17]. These offer increased surface areas, enhancing mass transport and binding capacities, facilitating, for example, an efficient interaction between immobilized molecules and target species.…”

The advancement of both porous materials and nanomaterials has brought about porous nanomaterials. These new materials present advantages both due to their porosity and nano-size: small size apt for micro/nano device integration or in vivo transport, large surface area for guest/target molecule adsorption and interaction, porous channels providing accessibility to active/surface sites, and exposed reactive surface/active sites induced by uncoordinated bonds. These properties prove useful for the development of different porous composition types (metal oxides, silica, zeolites, amorphous oxides, nanoarrays, precious metals, non-precious metals, MOFs, carbon nanostructures, MXenes, and others) through different synthetic procedures—templating, colloidal synthesis, hydrothermal approach, sol-gel route, self-assembly, dealloying, galvanostatic replacement, and so—for different applications, such as catalysis (water-splitting, etc.), biosensing, energy storage (batteries, supercapacitors), actuators, SERS, and bio applications. Here, these are presented according to different material types showing the evolution of the structure design and development towards the formation of hierarchical porous structures, emphasizing that the formation of porous nanostructures came about out of the desire and need to form hierarchical porous nanostructures. Common trends observed across these different composition types include similar (aforementioned) applications and the use of porous nanomaterials as templates/precursors to create novel ones. Towards the end, a discussion on the link between technological advancements and the development of porous nanomaterials paves the way to present future perspectives on these nanomaterials and their hierarchical porous architectures. Together with a summary, these are given in the conclusion.
