Surface electronic state modulation promotes photoinduced aggregation and oxidation of trace CO for lossless purification of H2 stream

Electrostatic induction promotes photocatalytic contaminant mineralization in saline wastewater

“…Aggregating contaminants in the vicinity of a photocatalyst can promote target collision to improve the utilization of photogenerated ˙OH. 7,8 This goal can be realized by strengthening the electrostatic interaction of contaminant molecules with the solid. 8 Generally, contaminants like phenols with polarity can offer electric dipole moment to form weak electrostatic attraction to a charged solid (Fig.…”
