Chen Zhigang group are interested in various aspects of science, ranging from fundamental research to possible industrial product development. Currently we are mainly recognized for the synthesis of micro-/nano porous materials and their applications, but with extensive collaborations with various research groups around Jangsu province, we are conducting research in the areas of adsorption, separation characteristics and its function in catalytic degradation of ecological environmental protection. We are particularly interested in organic or biological/inorganic interface chemistry including the molecular assembly of material systems with integrated nanoscale to macroscale functionalities. With inorganic material as the main object, the micro-/nano controlled structure design is carried out, and the preparation and the related basic research of the adsorption, catalysis and degradation are studied. Moreover, the porous classification matching theory is successfully developed, and the carbonaceous adsorption-light biodegradable materials have been exploited. The latter but the last, the photosynthetic bacteria to degradation of ammonia nitrogen, the magnetic photosynthetic bacteria degradation of ammonia nitrogen and the magnetic light catalyst degradation of organic pollutants research have been carried out. Specific as follows: 1)With natural attapulgite and expanded graphite as matrix, the design of high performance micro-/nano porous structure, and the basic and applied research of the organic or inorganic catalyst loading on the surface by physical assembly or chemical modification have been studied. 2)The matching effective control of micro-/nano porous inorganic materials (TiO2 and CeO2 etc.), ordered mesoporous crystal structure, and mesocrystal structure are prepared, and the adsorption and catalytic properties are studied. 3)The preparation technology of ultraviolet light and visible catalytic materials and performance of the related basic and applied research are carried out. 4)The photocatalytic and magnetic functional materials as the carrier to the rapid, efficient and deep pollutants purification and catalytic properties such as antibacterial sterilization research are discussed. 5)The adsorption, separation and degradation function in the environmental pollution (high concentrations of industrial waste water, environment poison gas, liquid pollutants, water pollutants, car tail gas, indoor pollution gas and industrial waste gas) by micro-/nano porous inorganic materials and related equipment researches are exploited.
