Efficient regulation of surface hydroxyl groups on a Pt/Na/AC catalyst using two-step nonthermal plasma for high formaldehyde oxidation performance

A novel catalyst (Pt/Na/AC (P&P)) with 0.1 wt% Pt loading was synthesized via a two-step nonthermal plasma method, achieving excellent HCHO oxidation performance at ambient temperature by tailoring surface hydroxyl groups on Na/activated carbon (AC).
