Abstract Crystalline red phosphorus (CRP), known for its promising photocatalytic properties, faces challenges in hydrogen evolution (PHE) due to undesired inherent charge deep trapping and recombination effects induced by defects. This study overcomes these limitations through an innovative strategy integrating ruthenium single atoms (Ru 1 ) within CRP simultaneously repair the intrinsic vacancy defects serve as uniformly distributed anchoring sites a controllable growth into nanoparticles NP ). Hence, highly functionalized with Ru 1‐NP /CRP) concerted regulating electronic structures promoting interfacial transfer has been achieved. Advanced characterizations unveil pioneering dual role of pre‐anchored (analogous “Tai Chi” principle) transforming photocatalysis. The regulations on surface minimize detrimental trapping, resulting prolonged lifetime active charges. With well‐distributed situ sites, constructed robust “bridge” that connects facilitates constructive transfer. Ultimately, synergistic effect endows /CRP exceptional PHE rate 3175 μmol h −1 g , positioning it one most efficient elemental‐based photocatalysts available. breakthrough underscores crucial pre‐anchoring metal at defect catalysts enhancing sustainable production.

Assessing the Structural Diversity of Form II Red Phosphorus via Stepwise Crystal Structure Search

Journal of the American Chemical Society, Год журнала: 2024, Номер 146(38), С. 26369 - 26378

Recently, the long less-known Form II red phosphorus (RP) (viz. Type RP) was ascertained by state-of-the-art 3-dimensional electron diffraction technique with a triclinic lattice, completely distinct from other known elemental and leaving atomic coordinates not determined. The cell composed of ∼250 atoms might exceed capacity current readily available crystal structure search packages, which have been widely applied to systems several tens atoms. Besides, mistaking RP for violet is still surprisingly common in studies on allotropic due misinterpretations JCPDS card #00-044-0906. Herein, reproducing annealing synthesis relaxation structures obtained literature, we verified two former be wrong explained how occurred. Then, basis experimental lattice data, provided possible models containing positions nearly exhaustive high-throughput stepwise approach optimized molecular mechanics, machine-learned force field, density functional theory succession. energetic stability found rank between white black phosphorus, similar nanorod modifications.
