The front cover artwork for Issue 12/2016 is provided by researchers from the University of Science & Technology of China. The image shows that hy
drogenated TiO
2 with an appropriate hy
drogenation time exhibits much higher photocatalytic H
2 evolution activity than that with an excessive hy
drogenation degree. See the Communication itself at
