Here, a MoOx-T based catalyst was developed by a simple reduction of MoO3 precursors at different temperatures. Interestingly, a partially reduced MoOx-600 catalyst obtained by reducing the MoO3 precursor at 600 °C shows the co-existence of a mixture of different valence states (0, +4, ∼+6) of Mo, and as a result, provides a superior catalytic activity.

In the present study, a sonochemical‐based method for one‐pot synthesis of entropy‐stabilized perovskite oxide nanoparticle catalysts with high surface area was developed. The high‐entropy perovskite oxides were synthesized as monodispersed, spherical nanoparticles with an average crystallite size of approximately 5.9 nm. Taking advantage of the acoustic cavitation phenomenon in the ultrasonication process, BaSr(ZrHfTi)O3, BaSrBi(ZrHfTiFe)O3 and Ru/BaSrBi(ZrHfTiFe)O3 nanoparticles were crystallized as single‐phase perovskite structures through ultrasonication exposure without calcination. Notably, the entropically‐driven stability of Ru/BaSrBi(ZrHfTiFe)O3 with excellent dispersion of Ru in the perovskite phase bestowed the nanoparticles of Ru/BaSrBi(ZrHfTiFe)O3 with good catalytic activity for CO oxidation.

Herein, we present a facile, sustainable, and highly efficient ionic liquid induced self-assembly protocol to construct a highly porous MnNbOx oxide with exceptionally high catalytic activity for NOx removal at low temperatures and excellent tolerance to H2O and SO2 poisoning.
