The tools of sol–gel chemistry allow synthesizing a plethora of functional materials in a controlled bottom-up fashion. In the field of heterogeneous catalysis, scientists utilize sol–gel routes to design solids with tailored composition, texture, surface chemistry, morphology, dispersion, etc. A field of investigation which shows great promises is that of hybrid heterogeneous catalysts. Examples are flourishing to show that catalysts featuring a combination of inorganic and organic components often display improved activity, selectivity, or even chemical stability as compared to the purely inorganic counterparts. Yet, classic sol–gel methods face some well-known limitations—related to the different reactivity of the precursors and to the high surface tension of water—which complicate the tasks of chemists, specifically for the synthesis of hybrid catalysts. Non-hydrolytic sol–gel (NHSG) chemistry appears as a pertinent alternative. Being realized in the absence of water, NHSG routes allow reaching an excellent control over the solid properties and on the distribution of the organic and inorganic components at the nano- and microscales. In this review, we briefly recapitulate the main types of non-hydrolytic sol–gel routes and we present the modified protocols to hybrid materials. Then, we present an overview of the non-hydrolytic sol–gel approaches that have been proposed to synthesize hybrid heterogeneous catalysts. For both Class I and Class II hybrids, we discuss how the NHSG technique has allowed tailoring the key properties that command catalytic performance. From this panorama, we argue that NHSG has a prominent role to play for the development of advanced hybrid heterogeneous catalysts.

溶胶-凝胶化学工具允许以受控的自下而上的方式合​​成大量功能材料。在非均相催化领域，科学家利用溶胶-凝胶路线设计具有定制组成，质地，表面化学，形态，分散性等特征的固体。研究领域显示出广阔的前景是混合型非均相催化剂。大量的例子表明，与纯无机物相比，具有无机和有机成分组合的催化剂通常显示出更高的活性，选择性甚至化学稳定性。然而，经典的溶胶-凝胶方法面临着一些众所周知的局限性-与前体的不同反应性和水的高表面张力有关-使化学家的工作复杂化，专门用于杂化催化剂的合成。非水解溶胶-凝胶（NHSG）化学似乎是一种适当的替代方法。在没有水的情况下实现的NHSG路线可以实现对纳米级和微米级的固体性质以及有机和无机成分分布的出色控制。在这篇综述中，我们简要概述了非水解溶胶-凝胶路线的主要类型，并向混合材料介绍了改进的方案。然后，我们介绍了已提出的用于合成杂化非均相催化剂的非水解溶胶-凝胶方法的概述。对于I级和II级混合动力车，我们将讨论NHSG技术如何允许定制控制催化性能的关键性能。从这个全景来看，
