通过简单的水热法成功合成了硫酸铜羟基硫酸铜Cu 4(OH)6 SO 4 -A和Cu 4(OH)6 SO 4 -B并作为非均相催化剂用于在氢气存在下的间歇式反应器中降解苯酚废水过氧化物(H 2 O 2)。研究了温度,H 2 O 2用量,初始pH和催化剂用量对苯酚和COD去除效率的影响,以获得最佳条件并更清楚地了解降解过程。铜2+还测量了反应三个小时后溶液中的浓度,以证明催化剂是稳定的。处理100和500 mg L -1苯酚废水时,苯酚去除效率达99%,COD去除效率达97%。即使催化剂具有低的比表面积,也主要存在中孔以降低对H 2 O 2和有机物的扩散控制。

hydroxysulphate 2 CuSO 4 ·1Cu(OH) 2 ·4 H 2 O and the hydroxyselenate 2 CuSeO 4 ·1Cu(OH) 2 ·4 H 2 O are very similar. The thermal decomposition of 2 CuSO 4 ·1Cu(OH) 2 ·4 H 2 O leads successively to the dihydrate 2 CuSO 4 ·1Cu(OH) 2 ·2 H 2 O, anhydrous 2 CuSO 4 ·1Cu(OH) 2 , dolerophanite (CuSO 4 ·CuO) and, finally tenorite (CuO). In the same way, the thermal decomposition of 2 CuSeO 4 ·1Cu(OH) 2 ·4 H 2 O leads
摘要 羟基硫酸盐2 CuSO 4 ·1 Cu(OH) 2 ·4 H 2 O 和羟基硒酸盐2 CuSeO 4 ·1 Cu(OH) 2 ·4 H 2 O 的制备方法非常相似。2 CuSO 4 ·1 Cu(OH) 2 ·4 H 2 O 热分解依次生成二水合物 2 CuSO 4 ·1 Cu(OH) 2 ·2 H 2 O、无水 2 CuSO 4 ·1 Cu(OH) 2 , 闪锌矿 (CuSO 4 ·CuO) 和,最后是钠长石 (CuO)。同样,2 CuSeO 4 ·1 Cu(OH) 2 ·4 H 2 O 的热分解首先导致无水化合物,然后是 CuSeO 3 ·CuO,最后是 CuO。X 射线粉末图表明,这些羟基硫酸盐和羟基硒酸盐是同晶型的,以 Z = 10 的三斜晶形式结晶。红外光谱表明氢键很弱,并且网络不受脱水的显着影响。
On Structural Features Necessary for Near-IR-Light Photocatalysts
In the search for photocatalysts that can directly utilize near‐IR (NIR) light, we investigated three oxides Cu3(OH)4SO4 (antlerite), Cu4(OH)6SO4, and Cu2(OH)3Cl by photodecomposing 2,4‐dichlorophenol over them under NIR irradiation and by comparing their electronic structures with that of the known NIR photocatalyst Cu2(OH)PO4. Both Cu3(OH)4SO4 and Cu4(OH)6SO4 are NIR photocatalysts, but Cu2(OH)3Cl
在寻找可直接利用近红外(NIR)光的光催化剂时,我们研究了三种氧化物Cu 3(OH)4 SO 4(鹿角石),Cu 4(OH)6 SO 4和Cu 2(OH)3 Cl通过在NIR辐照下对其进行光分解2,4-二氯苯酚并将其电子结构与已知的NIR光催化剂Cu 2(OH)PO 4进行比较。Cu 3(OH)4 SO 4和Cu 4(OH)6 SO 4均为近红外光催化剂,而Cu 2(OH)3 Cl不是。因此,除了两个不同的CuO的存在米和Cu'O Ñ多面体与铜联 ö 的Cu'桥梁,受体基团的存在(例如,SO 4,PO 4)与该金属氧多面体是必要用于近红外光催化剂。

edge-shared with TeO4 units. The layers are linked by slabs of corner-sharing CuO4 and SO4. Using both the bond valence sum analysis and magnetization data, we find purely Cu2+ ions within the layers but a mixed valence of Cu2+/Cu+ between the layers. Cu3(TeO4)(SO4)·H2O undergoes an antiferromagnetic transition at TN = 67 K marked by a peak in the magnetic susceptibility. Upon further cooling, a spin-canting

Copper hydroxyl sulfates Cu4(OH)6SO4-A and Cu4(OH)6SO4-B were successfully synthesized by a simple hydrothermal method and applied as heterogeneous catalysts to degrade phenol wastewater in a batch reactor in the presence of hydrogen peroxide (H2O2). The influence of temperature, H2O2 dosage, initial pH and catalyst dosage on phenol and COD removal efficiencies was investigated to get optimum conditions
