abstract = {Synergizing photocatalysis with external fields offers a promising strategy to surpass limitations of single catalytic systems, yet designing catalysts that works in multi-field remains challenging. In this work, we explore catalysts that improves photocatalysis in solution plasma to significantly enhance H2O2 production. We focus on bronze TiO2 and tune its crystallinity through an adjusted sodium titanate precursor route. In particular, the regular and wide tunnel structure of Na2Ti6O13 precursor results in bronze TiO2 with exceptional crystallinity. Upon introducing highly crystalline bronze TiO2 nanobelts into solution plasma, we effectively suppress the photocatalytic decomposition of H2O2 in plasma field, reducing the decomposition rate by 70% compared to commercial P25 TiO2 photocatalysts. Further carbon coating results in H2O2 concentrations up to 3.7 mmol/L, which is 1-3 orders of magnitude higher than most photocatalytic systems. Our work elucidates the potential photocatalytic effects within solution plasma and achieves synergy between photocatalysis and solution plasma.}
