Facile synthesis of CuMAl (M = Cr, Mn, Zn, and Co) with highly dispersed Cu and tailorable surface acidity for efficient 2-methylpyrazine synthesis

Abstract

Synthesis of 2-methylpyrazine requires the well-designed CuMAl catalysts with bifunctional sites. Through alternating M species (M = Cr, Mn, Zn, and Co), highly dispersed Cu⁰ and high surface acidity can be achieved, thereby approaching the optimized catalytic performance.
