通过尿素的高温聚合制备了片层状氮化碳g-C3N4，采用乙二醇还原法载铂得到Pt/g-C3N4催化剂。以X射线衍射(XRD)、X射线光电子能谱(XPS)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、傅里叶变换红外光谱(FT-IR)、比表面与孔隙度分析和电感耦合等离子体原子发射光谱(ICP-AES)等对所制备催化剂进行了表征，并在肉桂醛加氢反应中考察了其催化性能。结果表明，载体g-C3N4含有大量的含N基团，能有效稳定金属纳米粒子；Pt纳米粒子均匀分散在g-C3N4表面，且Pt粒径在2~3 nm之间；载体煅烧温度对催化剂的择性加氢性能有明显影响，550℃煅烧后的g-C3N4，所负载Pt在较温和的条件下表现出较明显的活性，肉桂醛转化率为30%，肉桂醇选择性为66%左右。重复使用3次，催化剂活性基本不变，具有良好的稳定性。
