Surfaces and interfaces play key roles in chemical material science. Understanding physical processes at complex surfaces is a challenging task. Machine learning provides powerful tool to help analyze accelerate simulations. This comprehensive review affords an overview of the applications machine study systems materials. We categorize into following broad categories: solid–solid interface, solid–liquid liquid–liquid surface solid, liquid, three-phase interfaces. High-throughput screening, combined first-principles calculations, force field accelerated molecular dynamics simulations are used rational design such as all-solid-state batteries, solar cells, heterogeneous catalysis. detailed information on for

Photoelectrochemical (PEC) water splitting represents a promising approach for harnessing solar energy and transforming it into storable hydrogen. However, the complicated 4-electron transfer process of oxidation reaction imposes kinetic limitations on overall efficiency. Herein, we proposed strategy by substituting with ethylene glycol (EG), which is hydrolysis byproduct polyethylene terephthalate (PET) plastic waste. To achieve this, developed synthesized BiVO

Abstract Photoelectrochemical (PEC) water splitting represents a promising approach for harnessing solar energy and transforming it into storable hydrogen. However, the complicated 4‐electron transfer process of oxidation reaction imposes kinetic limitations on overall efficiency. Herein, we proposed strategy by substituting with ethylene glycol (EG), which is hydrolysis byproduct polyethylene terephthalate (PET) plastic waste. To achieve this, developed synthesized BiVO 4 /NiCo‐LDH photoanodes capable achieving high Faradaic efficiency (FE) exceeding 85 % EG to formate in strongly alkaline environment. The mechanism was further elucidated using situ FTIR spectroscopy. Additionally, successfully constructed an unassisted PEC device hydrogen generation pairing translucent Mo : photoanode state‐of‐the‐art Cu 2 O photocathode, resulting approximate photocurrent density 2.3 mA/cm . Our research not only offers pathway converting PET plastics valuable chemicals but also enables simultaneous production.

BiVO4 has garnered considerable interest as a viable photoanode material for photoelectrochemical (PEC) water oxidation owing to its favorable bandgap and suitable band edge position. However, the PEC oxygen evolution property of pristine seriously suffers from poor surface kinetics rapid charge recombination. In this study, we demonstrate combination element doping heterostructure construction strategy, where Co-doped Fe3O4 (Co:Fe3O4) layer is decorated on Mo doped (BVO), which results in optimized transfer efficiency, transport boosted reaction (OER) active sites Co:Fe3O4/BVO photoanode. Consequently, achieves 1.9-fold better performance at 1.23 VRHE under 1 sun illumination, compared BVO. Furthermore, two-electrode system constructed by Pt wire shows high O2 rate 28.83 μmol cm–2 h–1 with Faradaic efficiency over 85%.
