Denitration of water was investigated by non-photocatalytic and/or photocatalytic processes (UV-A irradiation at 365 nm) using a mixture of Ag/P25 + Pt/P25 monometallic catalysts and Ag–Pt(Pt...

H 2 -temperature programmed reduction (H 2 -TPR analyses) show that the reduction by hydrogen is moderate for all the supports ( Fig. S3a and Table S2), due to the presence of a large...

MnCe/CNTs-I和MnCe/CNTs-M样品的H2-TPR图谱存在多个还原峰（低于600℃），这是由于MnOx的还原过程按MnO2→Mn2O3→Mn3O4→MnO的顺序进行，高于600℃时的还原峰对应CeO2→CeO过程，表明MnOx，CeOx，CNTs之间相互作用较弱。

TPR(Temperature Programmed Reduction)：惰性气体吹扫后，先吸附一种还原性气体（H2、CO等），然后再通入一定流量的惰性气体吹扫，并且升高温度，测量吹扫出来的气体的成分与浓度。

2000年3月13日 · During the reduction of pure titania (P25) under TPR conditions a maximum at 800 K (E-2) or 845 K (D-1, CH-1) is reported, corresponding to the consumption of 30 and 45 μmol H 2 /g, respectively. A second stage of reduction starts around 1050 K and is not finished until the maximum temperature is reached (E-2: 1140 K, D-1: 1273 K, CH-1: 1473 K).

2006年6月10日 · The effect of primary particle size of titanium dioxide on the reducibility of Pt/TiO 2 catalysts by carbon monoxide and hydrogen was investigated using temperature-programmed reduction (TPR) techniques and in situ Raman and Fourier transform infrared spectroscopy (FTIR). Experiments were conducted over Pt catalysts supported on four commercial ...

什么是h2-tpr？ TPR是程序升温还原。 指在程序升温（按照特定程序进行升温操作）过程中，使催化剂被H2还原的过程，从流出气体中测量还原 气体浓度 而判断其还原效果。

The inset shows the H2-TPR profiles for the four catalysts between 25 and 200 °C from publication: Active TiO2-Nanostructured Surfaces for CO Oxidation on Rh Model Catalysts at Low-Temperature...

H2-TPR和CO-TPR都是表征氧化物催化剂还原性能的技术，如果只是研究还原性能，在实验方面两者应该没有本质的差别。 不过，由于H2和CO的还原性能不同，TPR峰会有一定的差异。 然而，最大的差别在于，对于多组分催化剂，H2-TPR过程往往伴随着氢溢流的现象，使得还原峰的归属带来困难。 而CO-TPR可以避免溢流的干扰。 H2-TPR和CO-TPR都是表征氧化物催化剂还原性能的技术，如果只是研究还原性能，在实验方面两者应该没有本质的差别。 不过，由于H2和CO的 …

2014年12月1日 · To fundamentally understand the effects of deposited Pt and its deposition route on the photocatalytic reforming (PR) of glycerol for H2 evolution over Pt/TiO2, several 1 wt% Pt/P25 (PT) samples were prepared by photo-deposition (PD, glycerol as hole scavenger) and impregnation–reduction deposition routes (I
