Glycerol is a highly versatile molecule because of its three hydroxyl groups and can be transformed to a plethora of different value-added fine chemicals and products. It is an important byproduct in biodiesel production and, hence, produced in high amounts, which resulted in a high surplus flooding the market over the last decades. Thus, glycerol is regarded as a potential platform chemical, and many research efforts were devoted to find active catalysts to transform glycerol to various products via different catalytic processes. The selective oxidation reaction is one of the most promising reaction pathways to produce valuable fine chemicals used in the chemical and pharmaceutical industry. This Review describes the recent developments in selective glycerol oxidation to value-added products over heterogeneous catalysts. Particular emphasis is placed not only on newly developed catalysts based on supported noble-metal nanoparticles but also on catalysts containing nonprecious metals. The idea of using cost-efficient non-noble metals for glycerol oxidation is appealing from an economic point of view. Numerous parameters can influence the catalytic performance of the materials, which can be tuned by various synthetic approaches. The reasons for enhancements in activity are critically examined and put into perspective among the various studies. Moreover, during the past decade, many research groups also reported photocatalytic and, more scarcely, electrocatalytic pathways for glycerol oxidation, which are also described in detail herein and have otherwise found little attention in other reviews.

热，光和电催化甘油氧化的最新进展

甘油由于具有三个羟基，因此是一种用途广泛的分子，可以转化为多种不同的高附加值精细化学品和产品。它是生物柴油生产中的重要副产品，因此产量很高，在过去的几十年中，大量的过剩水淹没了市场。因此，甘油被认为是潜在的平台化学品，并且许多研究工作致力于寻找通过不同的催化方法将甘油转化为各种产物的活性催化剂。选择性氧化反应是生产化学和制药工业中有价值的精细化学品的最有希望的反应途径之一。这篇综述描述了在选择性催化甘油氧化为多相催化剂上增值产品方面的最新进展。特别重点不仅放在基于负载的贵金属纳米颗粒的新开发的催化剂上，而且还放在含有非贵金属的催化剂上。从经济的角度来看，使用具有成本效益的非贵金属进行甘油氧化的想法很有吸引力。许多参数会影响材料的催化性能，可以通过各种合成方法进行调整。在各种研究中，严格审查了增强活动的原因，并将其视为正确的观点。此外，在过去的十年中，许多研究小组还报道了甘油氧化的光催化途径，更是很少见的电催化途径，本文也对此进行了详细介绍，而在其他评论中却很少引起关注。
