This study reveals the influence of different TiO 2 supports on catalytic performance and phase transformations Co 3 O 4 during CO-PrOx.

Stochastic gradient algorithms estimate the gradient based on only one or a fewsamples and enjoy low computational cost per iteration. They have been widelyused in large-scale optimization problems. However, stochastic gradient algo-rithms are usually slow to converge and achieve sub-linear convergence rates,due to the inherent variance in the gradient computation. To accelerate...

CuCe mixed oxide is one of the most studied catalytic systems for preferential CO oxidation (CO-PrOx) purification hydrogen-rich gas stream. In this study, a series ceria supports were prepared via citrates-hydrothermal route by altering synthesis parameters (concentration and temperature). The resulting used preparation mixed-oxide catalysts wet impregnation. Various physicochemical techniques...
