The incipient-wetness impregnation process was made use of to load Ni on the reducible carrier TiO2 (P25). Within the method of catalyst preparation, the interaction and electronic effect between metal Ni and help TiO2 have been adjusted by changing the calcination temperature, and after that the activity and hydrogen production of glycerol steam reforming reaction (GSR) was explored. A series of modern characterizations which includes XRD, UV-vis DRS, BET, XPS, NH3 -TPD, H2 -TPR, TG, and Raman happen to be applied to systematically characterize the catalysts. The characterization final results showed that the calcination temperature can contribute to varying degrees of influences around the acidity and basicity with the Ni/TiO2 catalyst, the certain Antibacterial Compound Library site surface region, collectively with the interaction force among Ni as well as the help. When the Ni/TiO2 catalyst was calcined at 600 C, the Ni species might be made within the form of granular NiTiO3 spinel. Consequently, because of the moderate metal upport interaction and electronic activity formed between the Ni species and the reducible help TiO2 within the NiO/Ti-600C catalyst, the granular NiTiO3 spinel is usually lowered to a smaller sized Ni0 at a decrease temperature, and thus to exhibit the ideal catalytic efficiency.

Introduction Hydrogen energy has progressively attracted people’s research interest because it is regarded as a promising high-efficiency clean power and is widely made use of within the chemical and petroleum industries, specially in fuel cell energy generation [1,2]. On the other hand, the existing major supply of hydrogen production is from fossil power reforming, contributing to a large volume of carbon dioxide (CO2) gas emission as well; for instance, producing 1 ton of hydrogen from shale gas will release about 10 tons of CO2 gas [3]. Additionally, the physical state of hydrogen tends to make its storage and transportation tough, which is not conducive towards the usage of hydrogen [4]. It has been reported that hydrogen exists within a chemical type and it is then released via a catalytic process, which is a promising approach to resolve the storage and application of hydrogen [5].

Among various biomass liquid hydrogen carriers, glycerol is economically eye-catching and environmentally friendly, simply because of its advantage of somewhat high hydrogen content, non-toxicity, and easy storage.
