Agricultural runoff, fuel spillages, urbanization, hospitalization, and industrialization are some of the serious problems currently facing world. In particular, byproducts that hazardous to ecosystem have potential mix with water used for drinking. Over last three decades, various techniques, including biodegradation, advanced oxidation processes (AOPs), (e.g., photocatalysis, photo-Fenton oxidation, Fenton-like electrochemical process adsorption), filtration, adsorption been developed remove byproducts. Among those, AOPs, photocatalysis has received special attention from scientific community because its unusual properties at nanoscale layered structure. Recently, bismuth based semiconductor (BBSc) photocatalysts played an important role in solving global energy demand environmental pollution problems. bismuth-based Z-scheme heterojunction (BBZSH) is considered best alternative route overhaul limitations single-component BBSc photocatalysts. This work aims review recent studies on a new type BBZSH treatment contaminated water. The general overview synthesis methods, efficiency-enhancing strategies, classifications heterojunctions, degradation mechanisms Z- S-schemes, application organic dyes, antibiotics, aromatics compounds, endocrine-disrupting volatile compounds reviewed. Finally, challenges future perspective discussed.

Abstract Development of low‐cost electrocatalysts for water splitting is crucial to economical hydrogen production. Here, a highly efficient electrocatalyst composed MoNi 4 ‐embedded amorphous MoO 2 nanosheets grown on less‐tortuosity hierarchically porous carbonized wood (MoNi /MoO @CW) reported. The generation abundant heterointerfaces and defects‐rich significantly promote the adsorption activation reactant molecules @CW. obtained @CW catalyst exhibits ultralow overpotentials 22 205 mV evolution reaction oxygen at current density 10 mA cm −2 , respectively. can be used dual‐function electrodes assembling two‐electrode electrolyzer illustrates 1.47 V superior durability over 24 h overall electrolysis. Moreover, it also possesses high mass activity 142 Ag −1 200 mV, surpassing Pt/C (132 ). outstanding performance attributed decrease in energy barrier dissociation, optimal adsorption/desorption H/O‐intermediates, fast transport through structure, as confirmed by experimental results functional theory‐based calculations. has excellent potential practical splitting.

Significant efforts have been dedicated to hydrogen production through photocatalytic water splitting (PWS) over the past five decades. However, achieving commercially viable solar-to-hydrogen conversion efficiency in PWS systems remains elusive. These face intrinsic and extrinsic challenges, such as inadequate light absorption, insufficient charge separation, limited redox active sites, low surface area, scalability issues practical designs. To address these issues, conventional strategies including heterojunction engineering, plasmonics, hybridization, lattice defects, sensitization, upconversion processes extensively employed. More recently, innovative hybrid like photonic crystal-assisted polarization field-assisted emerged, which improve absorption separation by harnessing slow photon effect, multiple scattering, piezoelectric, pyroelectric, ferroelectric properties of materials. This review article aims provide a comprehensive examination summary new synergistic approaches, integrating plasmonic effects, processes, crystal photocatalysis. It also explores role temperature suppressing exciton recombination during photothermic highlights emerging effects magnetic fields, periodic illumination, many-body large-hole polaron, anapole excitations, hold significant potential advance technology facilitate renewable generation.

Solar-driven plastics conversion into valuable fuels has attracted broad attention in recent years, which enormous potential for recycling the future. However, it usually encounters low efficiency, where one of reasons is attributed to poor carrier dynamics photocatalytic process. In this Perspective, we critically review developed strategies, involving defect engineering, doping heterojunction and composite construction, boosted separation efficiency. addition, provide an outlook more strategies engineer catalysts promoted dynamics. Finally, also propose prospects future research direction photoconversion fuels.
