Welcome to My Group!

Dr. Qin works to promote the creation of the joint laboratory between Chulalongkorn University and Prof. Liu and Prof. Zhang group in Yanshan University, China. Our group is mainly engaged in research field of high strength and high hardness materials and composites, and the surface hardening and functionalization, such as high strength Zr alloy, diamond and related materials/composites, photocatalyst and energy storage materials/devices. We are focusing on the new high strength Zr alloy design and synthesis, control performance, surface hardening and functionalization, device design, and other systemic basic research.

In recent years,Dr.Qin’s group has conducted or participated in more than 10 projects such as Thailand Research Fund, National Research Council of Thailand, World Class Universities of Thailand, Chula Unisearch, Rachadapisek Sompoch Endowment of Chulalongkorn University, Chulalongkorn University, and Metallurgy and Materials Science Research Institute.

We welcome interested scholars and students with new ideas in the field of metal, alloy, nanomaterials and devices! Particularly welcome students interested in nano-research with good grades, positive initiative. And also welcome the exchanges and cooperation of experts and scholars at home and abroad!

MMRI Special Seminar “SOLAR FUEL PRODUCTION FROM WATER USING ORGANIC PHOTOCATALYSTS”
by Dr. REINER SEBASTIAN SPRICK
Department of Chemistry and Materials Innovation Factory, University of Liverpool, United Kingdom.

ABSTRACT

Photocatalytic hydrogen production from water is a research area of immense interest as hydrogen has been identified as a potential energy carrier of the future. Most of the studied photocatalysts are inorganic and organic materials have been far less studied, with the exception of carbon nitride materials. Here, I will present our work on the application of conjugated microporous polymers (CMPs),1-3 unbranched conjugated polymers,4,5 and covalent organic frameworks (COFs)6 as photocatalysts for hydrogen production from water. All photocatalysts were made from organic building blocks at low temperatures which allows for good control of their properties. I will discuss synthetic approaches in tuning of their light absorption and band alignment,7 crystallinity,6 particle size8 and wettability5,9 for improved photocatalytic activity.
Understanding of these systems was gained using transient absorption spectroscopy monitoring the temporal evolution of photogenerated reaction intermediates on slow and ultrafast timescales.5 This allowed us to draw a comprehensive picture of the processes that take place upon photoexcitation and to correlate the anion transient signal with the activity of the respective polymer. Furthermore, we used quasi-elastic neutron scattering to study water within the pores of CMP photocatalysts.3 We recently used automation to produce a large set of polymer photocatalysts that were studied for their performance. The data was then coupled with machine learning and we explored underlying factors beyond the ones previously considered by us in photocatalysis.
