Abstract

A straightforward and facile synthesis of cellulosic-carbon-shielded palladium–magnetic nanoparticle hybrid material (Pd-MNP@SCB) is presented here. Naturally abundant cellulose was isolated from waste sugarcane bagasse via simple base hydrolysis method and employed. Large surface area and porosity are crucial factors which can enhance the efficiency of a material in catalysis as well as energy storage application and the same was tried to achieve here using the cellulosic-carbon as a support. The prepared hybrid material was initially screened for its catalytic activity in Suzuki–Miyaura cross-coupling followed by its utilization in energy storage application. Pd-MNP@SCB could catalyze the cross-coupling reaction very efficiently with excellent functional group tolerance and good recyclability. The electrochemical performance was explored for Pd-MNP@SCB assembled in a two-electrode cell configuration. The maximum capacitance was found to be 121.74 F/g at a current density of 0.07 A/g with an excellent cycling stability of 97.69% over 3000 cycles.

一种绿色且可持续的纤维素碳屏蔽的Pd-MNP杂化材料，用于催化和能量存储应用

摘要

本文介绍了一种纤维素碳屏蔽的钯-磁性纳米粒子杂化材料（Pd-MNP @ SCB）的简单易行的合成方法。通过简单的碱水解方法从废甘蔗渣中分离出天然丰富的纤维素并使用。大的表面积和孔隙率是可以提高材料在催化以及能量存储应用中效率的关键因素，在此尝试使用纤维素碳作为载体来实现相同的目的。首先，对所制备的混合材料在铃木-宫浦交叉偶联中的催化活性进行筛选，然后将其用于储能应用中。Pd-MNP @ SCB可以非常有效地催化交叉偶联反应，具有出色的官能团耐受性和良好的可回收性。探索了在两电极电池配置中组装的Pd-MNP @ SCB的电化学性能。发现最大电容为121.74 F / g，电流密度为0.07 A / g，在3000个循环中具有97.69％的出色循环稳定性。
