      A series of C2-symmetric bis(phosphinite) ruthenium complexes bearing ferrocenyl moieties were developed and evaluated for catalytic activity towards transfer hydrogenation of acetophenone derivatives using 2-propanol in the presence of NaOH. Almost complete conversion and moderate to excellent enantioselectivity were obtained using all the complexes as catalysts at 82°C.

      A novel visible-light-driven g-C3N4/MIL-53(Al) composite photocatalyst was successfully prepared by a facile stirring method at room temperature and, for the first time, displayed optimal photocatalytic degradation efficiency. The g-C3N4(wt 20%)/MIL-53(Al) photocatalyst was about 5 times higher photocatalytic activity than the pure g-C3N4. A proposed mechanism for the enhanced photocatalytic activity was also discussed based on the experimental results.
