Published: Sept. 12, 2023

Abstract Fast production of hydrogen and oxygen in large amounts at an economic rate is the need hour to cater needs most awaited energy, a futuristic renewable energy solution. Production through simple water splitting via visible light photocatalytic approach using sunlight considered as one promising sustainable approaches for generating clean fuels. For this purpose, variety catalytic techniques novel catalysts have been investigated. Among these catalysts, carbon nitride presently deemed best candidates photocatalysis due its unique molecular structure adequate visible‐range bandgap. Its bandgap can be further engineered by structural morphological manipulation or doping/hybridization. numerous synthetic nitrides, supramolecular self‐assembly recently developed elegant bottom‐up strategies it bio‐inspired provides facile eco‐friendly route synthesize high surface area with superior features other semiconducting properties. The current review article broadly covers synthesis nanostructures their water‐splitting applications comprehensive outlook on future directions.

Shining light on ZnIn₂S₄ photocatalysts: Promotional effects of surface and heterostructure engineering toward artificial photosynthesis

EcoMat, Journal Year: 2022, Volume and Issue: 4(5)

Published: March 27, 2022

Abstract The gradual depletion of fossil fuel reserves that contribute to ~85% global energy production and release toxic effluents urges the transformation toward renewable fuels. Thus, sustainable utilization sunlight for water splitting CO 2 reduction with heterogeneous photocatalysts has come light. As a semiconductor photocatalyst, ZnIn S 4 hit limelight owing its narrow bandgap visible‐light‐responsive properties. However, limitations include limited active sites, fast charge‐carrier recombination, low photoconversion efficiency. Beginning from fundamental photocatalytic mechanism, this review then provides in‐depth insights into several modification strategies , extending defect engineering, facet cocatalyst loading junction enabling synergistic construction high‐performance ‐based systems. Subsequently, structure‐performance relation hydrogen evolution (HER), overall (OWS), applications in last years will be discussed concluded by future perspectives frontier. image

Small Structures, Journal Year: 2023, Volume and Issue: 4(7)

Published: Feb. 15, 2023

Photocatalysis‐self‐Fenton system (PSFs), which integrates photocatalysis with Fenton technology, is investigated thoroughly in wastewater treatment due to the virtues of no addition H 2 O and accelerated circulation Fe 2+ /Fe 3+ . Several kinds materials that mainly include metal‐free graphite carbon nitride (g‐C 3 N 4 ), metal oxides (Fe sulfide (CdS, FeS ) have demonstrated extensive development potential. Nevertheless, most developed catalysts are unable satisfy requirements PSFs. Therefore, a comprehensive review committed modification methods PSFs put forward. First, concrete mechanism from two aspects reaction discussed.
