Progress and future challenges in passive NO adsorption over Pd/zeolite catalysts

Autor: Huawang Zhao, Lei Ma, Alexander J. Hill, Johannes W. Schwank, Adarsh Bhat, Guohua Jing

Publikováno v: Catalysis Science & Technology. 11:5986-6000

Future emission standards are becoming increasingly stringent. Around 50% of targeted tailpipe emissions are emitted during the cold-start period, mainly due to the ineffectiveness of catalytic converters in the after-treatment system at low temperat

Stabilizing Highly Dispersed Halo Sites in Thermally Restructured Palladium Core@shell Nanoparticles for Improved Catalyst Activity and Durability

Autor: Alexander J. Hill, Andrej Lenert, Zachary J. Berquist, Johannes W. Schwank, Galen B. Fisher, Adarsh Bhat

Stabilizing high dispersions of catalytically active metals is integral to improving the lifetime, activity, and material utilization of catalysts that are periodically exposed to high temperatures during operation or maintenance. We have found that

Effect of Ce and la dopants in Co 3 O 4 nanorods on the catalytic activity of CO and C 3 H 6 oxidation

Autor: Xiaoyin Chen, Lei Ma, Johannes W. Schwank, Adarsh Bhat, Ping Li, Yongdan Li

Publikováno v: CATALYSIS SCIENCE AND TECHNOLOGY. 9(5):1165-1177

Ce and La doped Co3O4 nanorod catalysts were prepared and their catalytic activity for CO and C3H6 oxidation reactions was examined. XRD, TEM, XPS, TPR, TGA and in situ DRIFTS have been used to characterize structural properties, reducibility, mobili

Improving the thermal stability and n-butanol oxidation activity of Ag-TiO2 catalysts by controlling the catalyst architecture and reaction conditions

Autor: Johannes W. Schwank, Alexander J. Hill, Galen B. Fisher, Adarsh Bhat

Publikováno v: Applied Catalysis B: Environmental. 297:120476

We demonstrate a novel methodology of encapsulating and dispersing Ag nanoparticles in a reducible, mesoporous TiO2 nanosphere to enhance thermal stability and catalytic activity for VOC oxidation. Through comparisons with surface-impregnated Ag-TiO2

Structural Analysis of A Two-Wheeler Disc Brake

Autor: Bhaskar Pal, Devendra Dandotiya, Adarsh Bhat

Publikováno v: IOP Conference Series: Materials Science and Engineering. 1013:012024

Automotive brakes have come a long way, from drum brakes being widely used for a long time until disc brakes came along and began slowly wiping out the usage of drum brakes. This is primarily due to the number of advantages that the disc-pad setup br
