An Ambient Photocatalytic Approach to In‐Situ Prepare Cobalt/Cobalt Phosphide and Cobalt/Cobalt Phosphide@Graphene Heterojunction Nanomaterials With Optimized Charge Separation Effects for Highly Efficient Relayed Electrocatalytic NOX− Reduction to NH3

Carbon Energy, EarlyView.
A visible‐light‐driven ambient photocatalytic method in‐situ fabricates Co/CoP‐x and Co/CoP@rGO heterojunction with enhanced charge separation, enabling highly efficient relayed electrocatalytic NOx− reduction to NH3 with outstanding Faraday efficiency and ammonia productivity.

Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

Chemistry – A European Journal, EarlyView.
Sunlight‐driven synthesis offers a green and energy‐efficient route to metallic nanoparticles. Here, double‐vacancy halide perovskites (Cs2PtX6, X = Cl, Br) act as photoactive precursors for the in‐situ formation of ultrasmall (< 3 nm) platinum nanoparticles under simulated sunlight at room temperature.

The Asymmetric Self‐Replicative Alkylation of N‐Arylaldimines Using Organolithium Reagents

Chemistry – A European Journal, EarlyView.
Here, we report a new asymmetric autoinductive reaction; the addition of nBuLi to N‐arylaldimines to form chiral lithium amides. The reaction proceeds with full conversion and complete transfer of chirality, representing the first example of an asymmetric autoinductive reaction with organolithium reagents.

Breaking the Mold: Electrophilic Hydrophosphanation Emerges

Chemistry – A European Journal, EarlyView.
Electrophilic hydride attack on the olefin, instead of the classical nucleophilic addition by a phosphanido ligand, is unveiled in rhodium‐catalyzed olefin hydrophosphanation. This hydride‐driven pathway operates for both activated and inactivated olefins, with transition states characterized by elongated Rh─H bonds and nascent C─H bond formation ...
