Abstract: Selective catalytic reduction of nitrogen oxide by hydrogen (H2-SCR) is a newly developed effective method for nitrogen oxides elimination. The characteristics and current developments of H2-SCR are reviewed. Special attention is laid on the oxide and zeolite supported Pt and Pd catalysts employed in H2-SCR reaction and the corresponding H2-SCR reaction mechanism. Finally, future research on H2-SCR is proposed.
