Catal., ACS Catal., Chem Cat Chem, Catal. Sci. Tech) 和化学/综合期刊(JACS, Angew Chem, Nature Communications, Science等),获得超过6百万澳币的竞争性科研经费。他获得诸多学术奖项包括2019悉尼大学Grand Challenge Champion, 2018 SOAR Fellowship, 2017校长杰出研究奖,2015悉尼大学国际研究合作奖、2014欧盟玛丽居里研究与创新合作、2013悉尼大学Dean杰出研究奖、2012法国-澳大利亚科学创新合作青年研究奖、2011澳中低碳排放伙伴关系未来领袖。

Silica-alumina materials, particularly crystalline zeolites and amorphous silica-alumina (ASA), are among the most popular solid acids that have been widely commercialized as efficient and environmentally friendly catalysts in petrochemical industry. The formation of BAS in silica-alumina is based on aluminum centers distributed in the silica framework or network. The combined APT investigations and 27Al and 1H DQ-SQ NMR experiments revealed, for the first time, the existence of a synergy between Al species in the ASA network. This synergy can significantly enhance the acid strength of ASA. Understanding the cooperative action of metal and acid sites of bifunctional catalysts is essential for developing more efficient catalysts for greener chemical processes. We used in situ attenuated total reflection infrared (ATR-IR) spectroscopy in combination with modulation excitation spectroscopy (MES) and phase sensitive detection (PSD) to examine the functioning of Pd/silica-alumina (Pd/SA) catalysts with different acidity of the support in the liquid phase hydrogenation. Supported metal nanoparticles play key roles in nanoelectronics, sensors, energy storage/conversion, and catalysts for the sustainable production of fuels and chemicals. We applied in situ high-resolution transmission electron microscopy (HRTEM) photos and videos with correlating dynamics simulations to reveal the real time dynamic processes of nanocatalysts at high temperatures and the confinement of supports is of great significance to investigate nanoparticle structure and functions for practical utilization.
