The collaborative research from NSRRC scientists Yan-Gu Lin and Chao-Lung Chiang as well as NSRRC user Chi-Jung Chang was highlighted in the cover of
ACS Applied Materials & Interfaces
. The image illustrated the role of redox mediators monitored by operando synchrotron X-ray spectroscopy.
A collaborative research team led by Dr. Yan-Gu Lin and Dr. Chao-Lung Chiang of the NSRRC as well as Prof. Chi-Jung Chang of Feng Chia University used the experimental facilities at the NSRRC to monitor
in operando
the reaction mechanism of metal complex/ZnS photocatalysts. The research results were published in
ACS Applied Materials & Interfaces
and were featured as the inside front cover of the issue.
The research team reported the development of ZnS/metal complex photocatalysts and their improved photocatalytic activity toward H
2
generation. The hydrogen production rate was enhanced significantly and the maximum rate achieved 8,150 μmol

. Furthermore, the team employed operando experimental technique at TLS 17C1 to investigate the charge carrier dynamics of photocatalysis and to explain how the macrocyclic metal complex acted as a redox mediator. Their findings provide new insights for understanding the roles of redox mediators.
