Palladium (Pd) is considered as powerful catalyst in many organic syntheses of industrial importance, employed in areas like medicine, pharmacology, cosmetics, pesticides and degradation of organic pollutants. In heterogeneous catalysis, stabilization of Pd nanoparticles (NPs) is foremost to prevent aggregation for getting high catalytic efficiency. Celluloses, being green support, have been widely used in different forms such as bulk, modified or nanocelluloses for stabilizing Pd NPs. The unique properties like high mechanical strength, thermal stability, high functionality, insolubility in water and in most organic solvents and good anchoring ability with metal NPs had made them good support for Pd NPs. However, special attention is needed on further improving the binding efficiency of Pd NPs with cellulose without affecting the catalytic property for achieving long term recycle stability. This review will focus on the merits and demerits of the existing cellulose supported Pd catalysts and propose solutions to overcome the limitations.

钯（Pd）被认为是许多工业上重要的有机合成的有力催化剂，被用于医药，药理，化妆品，农药和有机污染物降解等领域。在非均相催化中，稳定Pd纳米颗粒（NPs）的主要目的是防止聚集以获得高催化效率。作为绿色载体的纤维素已经以不同形式广泛使用，例如本体，改性或纳米纤维素，用于稳定Pd NP。高机械强度，热稳定性，高功能性，在水和大多数有机溶剂中的不溶性以及与金属NP的良好锚固能力等独特性能使其成为Pd NP的良好支撑。然而，需要特别注意进一步提高Pd NP与纤维素的结合效率，同时不影响实现长期循环稳定性的催化性能。这项审查将集中于现有的纤维素负载Pd催化剂的优缺点，并提出克服这些限制的解决方案。
