CNT supported Mo_xC catalysts: Impact of loading and carburization parameters

, 2013
MoxC/CNT catalysts were prepared through carburization of an oxidic molybdenum precursor impregnated on multiwalled carbon nanotubes (CNTs). The effects of different carburization atmospheres, heating rates, and molybdenum loadings were tested.

Carburization Kinetics of Zircalloy-4 and Its Implication for Small Modular Reactor Performance

, 2022
Carburization of cladding materials has long been a concern for the nuclear industry and has led to the restricted use of high-thermal conductivity fuels such as uranium carbides. With the rise of small modular reactors (SMRs) that frequently implement a

Synthesis of tungsten carbide on Al-SBA-15 mesoporous materials by carburization [PDF]

, 2016
Aluminum was incorporated into SBA-15 supports at molar ratios Si/Al = 10 and 2 by the pH-adjusting method. The calcined mesoporous Al-SBA-15 supports, as well as the Al-free SBA-15 support, were impregnated with ammonium paratungstate ((NH4)(10)center ...
