Directed Charge Transfer‐Driven Efficient Photocatalytic Hydrogen Production in Dual S‐Scheme WS2/Co9S8/ZnCdS Heterojunction

Carbon Energy, EarlyView.
The photocatalytic hydrogen evolution reaction (HER) activity of the polyoxometalate (POM)‐derived dual S‐scheme heterojunction photocatalyst WS2/Co9S8/ZnCdS reaches a value as high as 15.66 mmol g−1 h−1 under visible light (λ ≥ 420 nm), providing a straightforward approach for the development of dual S‐scheme heterojunctions to enhance the efficiency ...

Phase‐Pure 2D Interfacial Perovskite Passivation for Stable and Efficient Photovoltaics

Carbon Energy, EarlyView.
Phase‐pure 2D interfacial passivation eliminates mixed‐phase energetic disorder, establishes favorable band alignment, and suppresses interfacial non‐radiative recombination. This review elucidates deterministic phase‐purity control, defect and lattice reconstruction mechanisms, and scalable manufacturing strategies, highlighting how phase‐pure 2D/3D ...

Silent Partners in the Mill: Unveiling the Role of Additives in Mechanochemical Synthesis

Chemistry – A European Journal, EarlyView.
Mechanochemistry offers a sustainable, solvent‐free alternative to traditional synthesis, often enhanced by additives in a process known as additive‐assisted grinding. This review discusses how various additives, including liquids, ionic solids, and advanced materials like ionic liquids and piezoelectric compounds, improve reaction efficiency ...
