Zhang, Wei, Naidu, Boddu S., Ou, Jian Zhen, O'Mullane, Anthony P., Chrimes, Adam F., Carey, Benjamin J., Wang, Yichao, Tang, Shi-Yang, Sivan, Vijay, Mitchell, Arnan, Bhargava, Suresh K., & Kalantar-zadeh, Kourosh (2015) Liquid metal/metal oxide frameworks with incorporated Ga2O3 for photocatalysis. ACS Applied Materials and Interfaces, 7(3), pp. 1943-1948.
Solvothermally synthesized Ga2O3 nanoparticles are incorporated into liquid metal/metal oxide (LM/MO) frameworks in order to form enhanced photocatalytic systems. The LM/MO frameworks, both with and without incorporated Ga2O3 nanoparticles, show photocatalytic activitydue to a plasmonic effect where performance is related to the loading of Ga2O3 nanoparticles. Optimum photocatalytic efficiency is obtained with 1 wt% incorporation of Ga2O3 nanoparticles. This can be attributed to the sub-bandgap states of LM/MO frameworks, contributing to pseudo-ohmic contacts which reduce the free carrier injection barrier to Ga2O3.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
