“…SBA-15 and CMK-3 structures have rod-type morphology. The obtained SEM images of SBA-15 and CMK-3 are good agreement with literature (Radhakrishnan et al, 2017;Zhu et al, 2019). EDX analysis of these materials shows that the template has only silica for SBA-15 and the CMK-3 sample has only carbon, confirming the success of the synthesis.…”

<p>In this study, an investigation was carried out in order to determine the potential of ordered mesoporous carbon including high ratio sucrose in its composition as a CO2 adsorbent. Structural characterizations of silica and carbon material were determined by using a scanning electron microscope (SEM), N2 adsorption/desorption and X-ray diffraction (XRD) analysis. CO2 adsorption capacities of developed adsorbent at various temperatures (25°C, 35°C and 50°C) were determined by using a thermogravimetric analyzer under CO2 flow. The maximum adsorption capacity was obtained as approximately 2.27 mmol g CO2 g-1 adsorbent which was remained almost the same in the desorption process. The first order reaction kinetic model was well fitted with the experimental data. Arrhenius equation was used to calculate activation energy which was obtained as -2.86 kJ mol-1 indicating barrier-less type adsorption. Results showed that ordered mesoporous carbon could be a potential source for an efficient and low-cost adsorbent for CO2 capture.</p>

“…Miao et al [13] developed a simplified solar evaporation system using floating structure with carbon nanotubes membrane as a light absorber and aerogel blanket as a thermally insulating layer, which attained a high evaporation efficiency of 84.6% at a light intensity of 1 kW m −2 . In this case, the most important part of solar evaporation system is the photo-thermal conversion material, which is directly related to harvesting solar energy, affecting the evaporation performance [14][15][16][17]. At present, metal (especially for Au, Ag) nanoparticles were reported as better photo-thermal conversion materials due to localized surface plasmon resonance (LSPR), which induced collective oscillation of charges in the metal nanoparticles to produce hot electrons [18][19][20][21].…”

Ag nanoparticles displayed a more attractive application in solar-driven interfacial evaporation for seawater desalination, but their synthesis process was expensive and detrimental to the environment due to the consumption of chemicals. In this work, we green-synthesized Ag nanoparticles using watermelon peel extract as reducing agent, while the membrane with Ag nanoparticles was prepared for solar-driven interfacial evaporation. Moreover, the evaporation performance of the membranes with different Ag nanoparticles loadings was investigated, as well as the reusability and desalination application was also explored. The experimental results showed that the membrane with Ag nanoparticles loading of 0.05 g exhibited superior evaporation performance, corresponding to the evaporation rate of 1.37 kg m −2 h −1 and the evaporation efficiency of 89.3%, respectively. In addition, the membrane with Ag nanoparticles possessed an excellent recyclability and concentration of ions in the desalinated seawater reached the potable water standard. Our research demonstrated that Ag nanoparticles green-synthesized by watermelon peel extract was an ideal candidate applied in solardriven interfacial evaporation for seawater desalination.
