Abstract
The effect of preparation conditions on the performance of Ni-based catalysts was investigated for glycerol steam reforming. La0.7Ce0.3NiO3 mixed oxides were synthesized using different solution concentrations and calcination temperatures by a co-precipitation method. Brunauer–Emmett–Teller, inductively coupled plasma, X-ray diffraction, temperature-programmed reduction, field emission scanning electron microscopy, CO2-temperature-programmed desorption, thermal gravity analysis, and Raman spectroscopy were performed to characterize the catalysts. With an La2NiO4 phase at lowest solution concentration, a catalyst precursor included an LaNiO3 phase instead of La2NiO4 at other solution concentrations. At a low calcination temperature of 700 °C, it was found that the smaller particle size of CeO2 incorporated more lanthanum and higher surface basicity, and the La2O2CO3 phase could effectively inhibit and eliminate coking leading to the better performance of catalysts.

%, which exhibits that Ni loading decreases dramatically with solution concentration declining to a certain extent
It is found that calcination temperature influences the textural properties of catalysts
Summary
With energy crisis and environmental issues, it is urgent to develop renewable energy resources. The use of biomass to obtain liquid fuels has received much interest, such as biodiesel with properties similar to diesel. Biodiesel as carbon neutral fuel is biodegradable and nontoxic and is derived from the transesterification of vegetable oils or animal fats by reacting with alcohol to produce approximately 10% (w/w) of crude glycerol. The profitability of biodiesel depends heavily on the economics of the byproducts. Glycerol is used mostly in the pharmaceutical, personal care, food, and cleaning industries. Glycerol is employed as a source of renewable hydrogen, which provides a promising solution for the dilemma of surplus glycerol
