Constructing and controlling of ruthenium active phases for acetylene hydrochlorination

Ru-based catalysts with distinct active phases from Ru0, RuO2, RuCl3 to RuCl2N were synthesized and evaluated in acetylene hydrochlorination. RuCl2N is identifed as the efficient active phase due to its co-activation of acetylene and hydrogen chloride. This discovery holds a great potential to accelerate the large-scale application of Ru-based catalysts in industry.
