The scalable fabrication of flexible membranes for efficient oil/water separation is in high demand but still significantly underdeveloped. Here, we present a membrane using Ti3C2T x (MXene) as the functional layer on conventional print paper substrate. With simple coating process MXene ink, developed highly hydrophilic and oleophobic with an underwater oil contact angle 137°. Such shows outstanding flexibility robustness, demonstrates facile approach scale-up ink low-cost paper. efficiency...
Sluggish kinetics of the anodic oxygen evolution reaction (OER) and minor upstream upsets in feed water quality remain bottlenecks for efficient electrolysis, which is exacerbated under near-neutral pH environments due to H2O dissociation. In this work, we report introduction a NiSx interlayer Co-(NiFe) oxide/nitride catalyst on nickel foam substrate. Postmortem OER characterization neutral synthetic seawater (SSW) shows that stable cationic [Co-(NiFe)]δ+ anionic [O-N]δ– surface species...
Transparent titania coatings have self-cleaning and anti-reflection properties (AR) that are of great importance to minimize soiling effect on photovoltaic modules. In this work, TiO2 nanocolloids prepared by polyol reduction method were successfully used as coating thin films onto borosilicate glass substrates via adsorptive self-assembly process. The characterized transmission electron microscopy x-ray diffraction. average particle size was around 2.6 nm. which an thickness 76.2 nm...
Abstract Carbon nanotubes (CNT) are robust and proven as promising building blocks for oil/water separating membranes. However, according to classic fluid dynamic theory, achieving high permeation flux without sacrificing other membrane properties is a formidable challenge CNT membranes, because of the trade-off nature among key parameters. Herein, relieve between fluxes, oil rejection rate, thickness, we present new concept engineer membranes with three-dimensional (3D) architecture. Apart...
Utilization of photocatalysis as a promising strategy for environmental and energy applications has been widely considered.

Metal-organic frameworks (MOFs) provide highly versatile platforms to stabilize molecular catalysts that are not readily accessible under homogeneous conditions, thus enabling access a new set of catalytic materials. Herein, we describe recyclable and active nickel catalyst immobilized on MOF for Suzuki-Miyaura coupling reaction, which operates mild conditions. This mixed ligand forms from the combination 1 equiv MOF-immobilized ligand, source, PPh3. The nature was verified through series...
Polymeric and ceramic asymmetric membranes have dominated commercial for water treatment. However, polymeric are prone to becoming fouled, while mechanically fragile.
