Heterogeneous photocatalysis and its potential applications in water and wastewater treatment: a review

Nanotechnology, Journal Year: 2018, Volume and Issue: 29(34), P. 342001 - 342001

Published: May 22, 2018

There has been a considerable amount of research in the development sustainable water treatment techniques capable improving quality water. Unavailability drinkable is crucial issue especially regions where conventional drinking systems fail to eradicate aquatic pathogens, toxic metal ions and industrial waste. The this area have given rise new class processes called advanced oxidation processes, particularly form heterogeneous photocatalysis, which converts photon energy into chemical energy. Advances nanotechnology improved ability develop specifically tailor properties photocatalytic materials used area. This paper discusses many those nanomaterials, both metal-based metal-free, studied for waste purification recent years. It also design performance recently reactors, along with advancements visible-light photocatalysis. Additionally, effects fundamental parameters such as temperature, pH, catalyst-loading reaction time reviewed. Moreover, different that can increase efficiency well recyclability systematically presented, followed by discussion on actual wastewater samples future challenges associated it.

Titanium dioxide (TiO₂)-based photocatalyst materials activity enhancement for contaminants of emerging concern (CECs) degradation: In the light of modification strategies

Chemical Engineering Journal Advances, Journal Year: 2022, Volume and Issue: 10, P. 100262 - 100262

Published: Feb. 8, 2022

Titanium dioxide (TiO2) as a photocatalyst has been ubiquitously studied for environmental applications. Though, readily available, nontoxic, and environmentally friendly; lower efficiency, less energy harvesting within the UV–Vis range with ease of photogenerated charge recombination is still concern its full-scale deployment remediation In light this, this mini review considers heteroatom doping, dye/metal sensitization, metal oxide/ semiconductor coupling, heterojunction constructions, surface morphology regulation well carbonaceous other nanomaterial hybrids improvement TiO₂ photocatalytic activity performance efficiency in removal contaminants emerging (CECs) from aqueous systems.

Designing Sites in Heterogeneous Catalysis: Are We Reaching Selectivities Competitive With Those of Homogeneous Catalysts?

Chemical Reviews, Journal Year: 2022, Volume and Issue: 122(9), P. 8594 - 8757

Published: March 3, 2022

A critical review of different prominent nanotechnologies adapted to catalysis is provided, with focus on how they contribute the improvement selectivity in heterogeneous catalysis. Ways modify catalytic sites range from use reversible or irreversible adsorption molecular modifiers immobilization tethering homogeneous catalysts and development well-defined solid surfaces. The latter covers methods for dispersion single-atom within supports as well complex nanostructures, it includes post-modification materials via processes such silylation atomic layer deposition. All these methodologies exhibit both advantages limitations, but all offer new avenues design specific applications. Because high cost most fact that resulting may limited thermal chemical stability, be best aimed at improving selective synthesis value-added chemicals, incorporated organic schemes, other applications are being explored address problems energy production, instance, greener processes. details each approaches discussed, representative examples provided. We conclude some general remarks future this field.
