| 3 | A confined growth strategy to construct 3DOM SiO_(2) nanoreactor insitu embedded Co_(3)O_(4) nanoparticles catalyst for the catalytic combustion of VOCs:Superior H_(2)O and SO_(2) resistance显示文摘SO_(2)poisoning is a common problem in the catalytic combustion of volatile organic compounds(VOCs).In this work,we took three-dimensionally ordered macroporous and mesoporous(3DOM)SiO_(2)as the nanoreactor to protect active sites from SO_(2)erosion in the catalytic combustion of benzene.Simultaneously,the confined growth of metal active nanoparticles in the multi-stage pore is also full of challenges.And we successfully confined Co_(3)O_(4)nanoparticles(NPs)in macroporous and mesoporous channels.Interestingly,the precursors’growth in the pore was controlled and nanoreactors with different pore sizes were prepared by adjusting the loading amount and preparation methods.It is discovered that the Co_(3)O_(4)NPs confined in 3DOM SiO_(2)nanoreactor showed superior sulfur and water resistance.Density functional theory(DFT)calculations verified that the Co-Si catalyst had high SO_(2)adsorption energy(-0.48 eV),which illustrated that SO_(2)was hard to attach to the surface of the Co-Si catalyst.The SiO_(2)nanoreactor had low SO_(2)adsorption energy(-5.15 eV),which indicated that SO_(2)was easily absorbed on SiO_(2)nanoreactor.This illustrated that the SiO_(2)nanoreactor could protect effectively active sites from SO_(2)erosion. | Weigao Han Shilin Wu Fang Dong Weiliang Han Yinghao Chu Linghui Su Zhicheng Tang | 2024 | Nano Research2024，17，1： | 0 |
| 4 | 修饰添加物对超临界碳氢燃料裂解结焦的影响显示文摘H使用催化剂催化裂解碳氢燃料来提高热沉具有巨大的应用潜力,但裂解结焦的问题限制了其进一步的发展,本文利用钴氧化物及表面有机化修饰的分子筛,进行管内催化裂解超临界碳氢燃料(C8,C10,C12)的研究,选取最高热沉的一组催化剂(3%Co_(3)O_(4)负载量,质量分数0.1%)进行结焦过程的分析,结果表明,温度较低的前段(300 mm前)主要是热裂解二次聚合成焦,在中段(约700 mm),随着温度的提高,催化作用开始显现,管壁的元素通过渗透作用进入到逐渐积累形成的焦炭中,在后段(700 mm后),催化剂作用逐渐减弱,管壁焦体大面积迅速脱落更新,最终完全堵塞管路。 | 龙琳 蓝振仲 吴传伟 邱云峰 周伟星 | 2022 | 工程热物理学报2022，43，5： | 0 |
| 5 | 单质Ag修饰Co_(3)O_(4)的高活性Li-O_(2)电池催化剂的制备及性能显示文摘以金属有机框架-74为模板制备了仿锤体状Co_(3)O_(4),然后与单质Ag复合,通过界面工程提高了材料电导率,制备出Li-O_(2)电池的高活性催化剂Ag/Co_(3)O_(4)。在100 m A/g电流密度,使用Ag/Co_(3)O_(4)催化剂的Li-O_(2)电池的放电比容量达到了13945 m A·h/g,即使在1000 m A/g高电流密度,依然可以保持4476.3 m A·h/g的放电比容量,证明其具有出色的倍率性能。同时,循环性能也得到了大幅提高,在电流密度为500 m A/g,限制比容量为1000 m A·h/g,使用Ag/Co_(3)O_(4)催化剂的电池可以稳定循环195圈,而使用Co_(3)O_(4)催化剂的电池只能循环42圈。 | 赵亚君 汪晓敏 罗浩 张大伟 | 2022 | 硅酸盐学报2022，50，1： | 0 |
