Effect of Mn and Ce oxides on low-temperature NH3-SCR performance over blast furnace slag-derived zeolite X supported catalysts
Lin Chen,Shan Ren,Yanhua Jiang,Lian Liu,Mingming Wang,Jie Yang,Zhichao Chen,Weizao Liu,Qingcai Liu +8 more
TL;DR: In this paper , the authors investigated low-temperature NH3-SCR performance of several Mn and/or Ce oxides on blast furnace slag-derived (BFS-derived) zeolite X catalysts and found that Mn-Ce/X catalyst had the highest NO conversion of nearly 98% at 250 °C and excellent N2 selectivity of nearly 100% during 75-175 °C.

Synthesis of three-dimensionally ordered macroporous composite Ag/Bi2O3–TiO2 by dual templates and its photocatalytic activities for degradation of organic pollutants under multiple modes
TL;DR: In this article, polystyrene latex spheres and triblock copolymer surfactant EO20PO70EO20 were used simultaneously as dual templates, with TiO2 as a substrate to fabricate the three-dimensional ordered macroporous composite Ag/Bi2O3-TiO2 by a sol-gel method and post-processing calcination.

Construction of Fe2O3 loaded and mesopore confined thin-layer titania catalyst for efficient NH3-SCR of NOx with enhanced H2O/SO2 tolerance
Kai Guo,Kai Guo,Jiawei Ji,Ryota Osuga,Yuxiang Zhu,Jingfang Sun,Changjin Tang,Changjin Tang,Junko N. Kondo,Lin Dong +9 more
TL;DR: Li et al. as discussed by the authors constructed thin-layered titania confined in mesoporous silica via a surface grafting strategy, which exhibits high specific surface area with amorphous structure along mesopore channel, and much more Bronsted acid sites are generated than bulk TiO2 due to defect induced oxygen-related species.
