“…35 The absorption peak appearing at 534 cm −1 corresponds to the Ti−O stretching (signal from Ti 2 O 3 , black curve). 36 All of the characteristic peaks of PVA and Ti 2 O 3 appear in the LASH sample (blue curve), confirming the presence of Ti 2 O 3 nanoparticles in the PVA matrix. Moreover, there is a new absorption band at 1084 cm −1 , which results from the interaction between the PVA matrix and Ti 2 O 3 nanoparticles.…”

Synergistic Energy Nanoconfinement and Water Activation in Hydrogels for Efficient Solar Water Desalination

Precisely controlled distribution of energy in solar-to-thermal energy conversion systems could allow for enhanced energy utilization. Light-absorbing hydrogels provide a means for evaporating water by using solar energy, yet targeted delivery of solar thermal energy to power the water evaporation process remains challenging. Here, we report a light-absorbing sponge-like hydrogel (LASH) that is created by in situ gelation of a light-absorbing nanoparticle-modified polymer, leading to synergistic energy nanoconfinement and water activation. By experimental demonstration and theoretical simulation, the LASH presents record high vapor generation rates up to ∼3.6 kg m–2 h–1 and stable long-term performance under 1 sun (1 kW m–2) irradiation. We investigate the energy confinement at the polymer–nanoparticle interphases and the water activation enabled by polymer–water interaction to reveal the significance of such effects for high-rate solar vapor generation. The water vaporization enabled by LASHs can remove over 99.9% of salt ions in seawater through solar water desalination. The fundamental design principle, scalable fabrication route, and superior performance offer possibilities for portable solar water purification, industrial solar-powered water treatment, and other advanced solar thermal applications.

“…The resulting long peaks corresponding to different impurities were not found to be present in XRD spectra, confirmed the high purity of synthesized polymer capped ZnO nanoparticles. For comparison purpose, the Debye-Scherer's equation was used, [38][39][40] as DS = 0.9λ/(β cos θ), to compute the size of dyes D 1 and D 2 capped ZnO nanoparticles. In this equation, DS is crystallite size, β is the full width at half maxima (FWHM), λ is the wavelength of the copper (Cu) radiation.…”

This article describes the synthesis, characterization and photo‐physical studies of ZnO nanoparticles capped with monomer and polymer dyes D1 and D2, respectively; these dyes were synthesized by an easy and inexpensive condensation method by reacting Indole‐3‐carboxaldehyde with N,N‐dimethylethylenediamine and polyamine. The optoelectronic properties of these dyes were investigated by UV‐Vis spectroscopy. Further, these dyes D1 and D2 were decorated with ZnO nanoparticles and labelled as samples S1 and S2. The structural properties of dyes capped ZnO nanoparticles were characterized by X‐ray diffractogram, scanning electron microscopy, and dynamic light scattering studies. Further, S1 and S2 were deployed to fabricate photo‐anodes for ZnO solar cells, labelled as SC1and SC2, respectively. The results of investigations revealed that polymer dye molecules enhanced the photo‐harvesting capability of ZnO nanoparticles within the ZnO solar cell SC1. Maximum photo‐energy conversion efficiencyη =5.42 % was attained with solar cell SC2 under AM 1.5 solar irradiations. Comparatively, it has been observed that the recorded photovoltaic efficiency of solar cell SC2 was enhanced by 1.49 % comparative to the solar cell SC1. The IPCE spectra studies revealed a significant improvement of (15–19)% in the photo efficiency of solar cell SC2 than SC1.

“…[20] Recently, nanostructured phenolic polymers and their derived porous carbons have received considerable research interests, which exhibit large surface areas, good thermostability and high carbon yields. [21][22][23][24][25][26] It has been reported that the silica spheres were successfully synthesized using hydrolysis and condensation way of silicon alkoxides compounds by the classical Stöber method. [27] According to the similar sol-gel synthesis mechanism, researchers have used analogous methods to triumphantly synthesize phenolic resin nanospheres by the polymerization on phenol and aldehydes.…”

The replacement of Pt/C catalysts with ironÀ nitrogenÀ carbon (FeÀ NÀ C) nanomaterials in the oxygen reduction reaction (ORR) is appealing for the large-scale application of fuel cells. Herein, an extended Stöber method was used to in situ synthesize FeÀ N co-doped porous carbon spheres (FeÀ NÀ Cs) with large surface areas and impressive ORR performance. FeÀ NÀ Cs were synthesized using 3-aminophenol as N precursor, ferrocenealdehyde (FcÀ CHO) as Fe source and crosslinker, and Pluronic F127 as soft template. Among all prepared catalysts, FeÀ NÀ Cs-1.0
