High-Pressure Torsion for Highly-Strained and High-Entropy Photocatalysts

Nowadays, the environmental crisis caused by using fossil fuels and CO2 emissions has become a universal concern in people’s life. Photocatalysis is promising clean technology to produce hydrogen fuel, convert harmful components such as CO2, degrade pollutants like dyes water. There are various strategies improve efficiency of photocatalysis so that it can be used instead conventional methods; however, low process remained big drawback. In recent years, high-pressure torsion (HPT), severe plastic deformation (SPD) method, shown extremely high potential an effective strategy activity photocatalysts synthesize new highly efficient photocatalysts. This method successfully increasing light absorbance, narrowing bandgap, aligning band structure, decreasing electron-hole recombination, accelerating separation introducing large lattice strain, oxygen vacancies, nitrogen phases, heterojunctions, high-entropy ceramics. study reviews findings on improvement HPT processing discusses parameters lead these improvements.
