Research


For the in-depth understanding of the structure and properties of naturally occurring minerals as well as the high-efficiency applications of mineral resources, I and my colleagues are being dedicated to the mineralogical studies covering comprehensive aspects. These studies are focused on the following topics: (1) the structure and the related phase transformation behaviors of mineral; (2) the surface-interface chemistry of mineral and its influences on the performances of mineral as a basic medium in the geo-systems; (3) the methodology and the related mechanisms for the characterization of the inherent or post-endued properties of minerals, and their uses in the fields of mineral-based/related materials. These topics combines diversity of the projects starting from the contributions of clay minerals for the hydrocarbon formation to the selective functionalization of mesopores in mineral nanotube, and this diversity was set up based on an expectation that the most profound discoveries of today’s mineralogical science would be happening at the interfaces of different disciplines.

Specifically, my current projects include the surface acidity of clay minerals and its effects on the formation of hydrocarbons, the surface modification of nanosized tubular halloysite for the uses of loading, and the structural modification of macroporous/mesoporous opal-A for the adsorption applications.
