Catalytic mechanism of NiO on the conversion fructose to methyl lactate (MLA) has been evaluated in this work. NiOs were calcined at various temperatures. NiOOH was detected on the surface of NiO. The amount of NiOOH as well as the product yield of MLA decreased with an increase in the calcination temperature of NiO. We have demonstrated that NiOOH could facilitate the catalytic conversion of fructose to MLA. This work provides some new insights into the NiO catalytic production of MLA. These results will guide the preparation of nickel based solid catalysts for the MLA production.

NiO催化将果糖转化为乳酸甲酯的新见解

在这项工作中，已经评估了NiO催化果糖转化为乳酸甲酯（MLA）的催化机理。NiO在各种温度下煅烧。在NiO的表面检测到NiOOH。NiOOH的量以及MLA的产物收率随着NiO煅烧温度的升高而降低。我们已经证明，NiOOH可以促进果糖向MLA的催化转化。这项工作为MLA的NiO催化生产提供了一些新见解。这些结果将指导MLA生产中镍基固体催化剂的制备。
