The current appeal for sustainable chemistry urgently needs to develop a facile and green method for the synthesis of highly efficient catalysts. Herein, for the first time, a highly skilled catalyst was prepared by photodeposition (PD) of Pt nanosites on the titanium nitride (TiN) under the illumination of Xe lamp in a short period. The resulted Pt/TiN-pd had uniformly dispersed particle sizes (∼2.2 nm) and a high reduction degree, which exhibited high phenol conversion (641 mol/mol_Pt h and cyclohexanone selectivity (∼82 %) under mild reaction conditions (50 °C and 0.5 MPa). Characterizations by the XRD, XPS, DRUV-vis, HRTEM, etc., have revealed the intensified metal-support synergy assisted by the photo-irradiation. It not only facilitated the close contact between Pt species and TiN support to constrain the metal sintering but also promoted their charge transfer as a result of the surface plasmon resonance effect. This simple strategy of photodeposition noble metals on TiN affords a time-saving and structure-tunable alternative to attain highly efficient catalysts for sustainable chemical transformation.

当前对可持续化学的呼吁迫切需要开发一种简便且绿色的方法来合成高效催化剂。在此，首次在短时间的氙灯照射下，通过在氮化钛（TiN）上对Pt纳米位进行光沉积（PD）来制备高技术的催化剂。所得的Pt / TiN- pd具有均匀分散的粒径（〜2.2 nm）和高还原度，表现出高的苯酚转化率（641 mol / mol _Pth和在温和的反应条件（50°C和0.5 MPa）下的环己酮选择性（〜82％）。通过XRD，XPS，DRUV-vis，HRTEM等进行的表征揭示了在光辐照的辅助下金属载体协同作用增强。它不仅促进了Pt物种与TiN载体之间的紧密接触以约束金属烧结，而且由于表面等离振子共振效应而促进了它们的电荷转移。这种在TiN上光沉积贵金属的简单策略提供了一种省时和结构可调的替代方案，从而获得了实现可持续化学转化的高效催化剂。
