Hydrogen production from catalytic formic acid ecomposition over Zn based catalysts under room temperature

The depletion of petroleum sources and global warming issues has increased awareness among scientists to produce alternative energy other than the one that we always depend on, which is petroleum. Hydrogen (H2) energy is one of the alternatives that was promising as an efficient and green fuel. Me...
