Adsorptive desulfurization using Cu–Ce/metal–organic framework: Improved performance based on synergy between Cu and Ce

Functionalization of SBA-15 with CeO2 nanoparticles for adsorptive desulfurization: Matters of template P123

“…There is great potential in using adsorbents for deep desulfurization, because organic sulfur molecules can be captured at ambient conditions with high efficiency (Song et al, 2014;Vilarrasa-Garcia et al, 2011b;Xiong et al, 2010). It is commonly known that both p complexation and direct sulfur metal (S-M) bonds can work for adsorptive desulfurization (Danmaliki and Saleh, 2017;Khan et al, 2017;Shi et al, 2017Song et al, 2013. Thus, active species, such as Cu 2 O (Jiang et al, 2013;Wang et al, 2009b), CeO 2 Xiao et al, 2013a), etc.…”

Construction of Cu–Ce/graphene catalysts via a one-step hydrothermal method and their excellent CO catalytic oxidation performance

“…According to the literature, 22 the absence of peaks at about 932 eV was characteristic of the reduced copper species, which included Cu 0 and Cu + . Khan et al 23 attributed the peak at about 932 eV to the presence of Cu + . However, Chen et al 24 reported that Cu + was only the intermediate transition state, which was beneficial for promoting the conversion of Cu 2+ to Cu 0 at high temperatures.…”

Adsorptive removal of herbicides from water over nitrogen-doped carbon obtained from ionic liquid@ZIF-8

“…The adsorption results were analyzed with a pseudo-second-order non-linear kinetic model [69], Langmuir isotherm [70], and separation factor [71]. The effect of pH on DUR and 2,4-D adsorption over IMDC was studied by adjusting the solution pH by adding small amounts of 0.1 M HCl or NaOH solutions.…”

“…The rapid adsorption of both adsorbates over IMDC suggests that specific interactions occur between IMDC and the adsorbates. The maximum adsorption capacities (Q 0 ) and b-values of the studied adsorbents were calculated from their corresponding Langmuir plots [70,75] (shown in Fig. S1) and are summarized in Table 4.…”
