For sake of comparison, different reduction temperatures were also applied to the Ni(post)/TiO2(PC500) catalyst. Similarly to the Ni/TiO2(PC500) catalyst, a decrease in the HMF conversion was observed with the increase in the reduction temperature, as well as only a partial switch to the selectivity pattern, with the production of both 5-MF and BHMF with moderate selectivities to 5-MF and BHMF of 24% and 68%, respectively. Very low yields to 5-MF and BHMF of 9% and 25 were obtained, respectively.
