Diffuse reflectance spectra for titanium dioxide, graphitic carbon nitride, and their composites

Diffuse reflectance spectra for titanium dioxide (TiO2), graphitic carbon nitride (g-C3N4), and their composites annealed at 200 and 300 oC. Bulk graphitic carbon nitride was prepared by polymerizing pure urea at 600 oC. Sol of TiO2 nanoparticles was annealed at 200 and 300 oC. Composites of TiO2 with g-C3N4 were prepared by adding urea to the TiO2 sol, lyophilizing the resulting mixture, and then annealing it at 200 and 300 oC.

本数据集包含二氧化钛（TiO₂）、石墨相氮化碳（g-C₃N₄）以及二者经200℃和300℃退火处理所得复合材料的漫反射光谱数据。其中，本体石墨相氮化碳通过在600℃下聚合纯尿素制备；二氧化钛纳米颗粒溶胶分别在200℃与300℃下进行退火处理；二氧化钛与石墨相氮化碳的复合材料制备流程为：向二氧化钛溶胶中加入尿素，将所得混合体系进行冷冻干燥，随后分别在200℃和300℃下退火得到。
