A catalyst consisting of single-atom Ru sites supported on an N-MXene (Ti ₃ C ₂ T x ) was developed for pH-universal hydrogen generation based on theoretical predictions, whose performances are comparable to and better than those of Pt/C.

The performance and cost of electrocatalysts play an important role in the development and application prospects of energy conversion technology.

PLQE enhancement and emission manipulation have been achieved for zero-dimensional (MA) ₄ InCl ₇ through a metal ion doping strategy. Cs ⁺ or Mn ²⁺ doping result in defect passivation and homogeneous crystals, while Sb ³⁺ doping shift the emission center.
