I am a student of physical chemistry. my MSc research was on study of adsorption of some industrial dyes from waste water. so I now want to do my PhD in heterogeneous catalysis and in a university in China. after a thorough research I found out that Xiamen university has what I am looking for. First, they offer English language medium PhDs. second, they have the expertise I am looking for in terms of application of heterodeneous catalysts in the conversion of biomass materials. Lastly the university has a good ranking.
