Recent advances in boosting interfacial bubble dynamics with external fields

Droplet, EarlyView.
External physical fields, including acoustic, magnetic, thermal, mechanical, and optical stimuli, accelerate the entire bubble‐dynamics sequence of nucleation, growth, and detachment. Abstract The efficiency of industrial electrocatalytic reactions depends not only on generating gaseous products but also on their detachment from the catalyst surface ...

Boosting Charge Separation in a CdIn2S4/Mo2TiC2 MXene Schottky Heterojunction for Enhanced Photocatalytic Hydrogen Production

EcoEnergy, EarlyView.
ABSTRACT Mo2TiC2 MXene was exfoliated in situ using hydrofluoric acid solution and subsequently integrated with CdIn2S4 through physical stirring and grinding. The composite material demonstrated exceptional photocatalytic hydrogen evolution (PHE) activity without the loading of any noble metal co‐catalysts, achieving a hydrogen production rate as high
