Fan J., Fan X., Fan J., Fan X., Hu X., Liu E., Kang L., Tang C., Wu H., Li Y., Liu E., Ma Y., Northwest University, CN

Recently, studies revealed that noble metal (Au, Ag, Pd) nanoparticles can improve the photoresponse property of TiO2 in the visible region based on the localized surface plasmon resonance (LSPR) effect, and thus enhance the activity [...]

Application of alumina-based nanogold catalysts in gas mask and CO2 laser

Qi C., Su H., Sun X., Guan R., Lin H., Sun X., Zheng Y., An L., Yantai Univeristy, CN

We have found that Au nanoparticles on Al2O3 (a popular commercially available support material) show surprisingly high activities for CO oxidation when properly prepared [6-11]. Our proprietary catalyst, Au deposited on a ferrite-modified alumina prepared [...]

Alumina extraction from fly ash by the MgO sintering method: Waste reduction and utilization

Zhao L., Sun Q., Wang B., Wang X., Wang B., Wang X., Xiao Y., Yu G., Liu X., Zhang Z., National Institute of Clean-and-low-carbon Energy (NICE), CN

In recent years, many methods for the alumina extraction from fly ash have been tested, developed and demonstrated in China. Generally, alkali sintering methods are more easily deployed than acid leaching methods, but it is [...]
