AIBN Special Seminar: Prof Junhu Wang, Dalian Institute of Chemical
Title: Novel catalytic Materials for environment and energy.
Date: Friday 2 November
Venue: AIBN, Level 1 Seminar Room
Recent years, our research focus on the development & characterization of the novel nano-composite materials applied for environmental purification and energy catalysis. Our main research topics:
1) In situ Mössbauer investigation combined with other spectroscopic studies (such as XAFS and so on) on the structural properties and mechanism of iron and/or tin containing catalytic materials;
2) Nano catalytic materials of noble metal with special morphology;
3) Hydroxyapatite-based catalytic materials with high efficiency.
This talk is to present a highly active and sintering-resistant Au/FeOx-hydroxyapatite catalyst for CO oxidation.
Despite of the high activity and extensive potential applications of supported gold catalyst, one problem is the sintering of nano-gold at high temperatures (e.g. ≥ 400 oC), which will constrain its practical applications. Several strategies such as utilizing mesoporous materials to confine gold particles, using mixed or surface-modified oxide supports, developing new supports like metal phosphates have been adopted to address this problem. These strategies certainly improve the anti-sintering ability at high temperatures. However, they usually arouse other problems such as use of expensive precursor, decrease of activity and/or even deactivation on stream. Therefore, it is still a challenge issue and remains large space to explore new material and/or new method for gold catalyst preparation to address this problem.
Recently, hydroxyapatite [HAP, Ca10(PO4)6(OH)2]
based functional materials have attracted more and more attentions as
recyclable catalysts and/or catalyst carriers due to its structural
designability, bifunctionality, adsorption and ion-exchange ability.
HAP contains abundance of PO43- and
