Manageable Bubble Release Through 3D Printed Microcapillary for Highly Efficient Overall Water Splitting

Advanced Science, Journal Year: 2023, Volume and Issue: 10(13)

Published: Feb. 24, 2023

Porous metal foams (e.g., Ni/Cu/Ti) are applied as catalyst supports extensively for water splitting due to their large specific area and excellent conductivity, however, intrinsic bubble congestion is unavoidable because of the irregular three-dimensional (3D) networks, resulting in high polarization degraded electrocatalytic performances. To boost H2 O decomposition kinetics, immediate removal supply sequential gas-liquid-solid interface essential. Inspired by efficiency water/nutrient transport capillaries plants, this work designs a graphene-based capillary array with side holes support manage release via Z-axis controllable digital light processing (DLP) 3D printing technology. Like planting rice, low-cost, high-active CoNi carbonate hydroxide (CoNiCH) planted on support. A homemade cell can reach 10 mA cm-2 1.51 V, be kept at 30 60 h without noticeable degradation, surpassing most known cells. This research provides promising avenue design prepare advanced catalysts various fields, including energy applications, pollutant treatment, chemical synthesis.

Sb/X (X = Mn, Er, Ho) Co‐Doped Lead‐Free Double Perovskite Cs₂NaInCl₆ for Single‐Component White Light Emission

Advanced Optical Materials, Journal Year: 2024, Volume and Issue: 12(12)

Published: March 14, 2024

Abstract Recently, the incorporation of transition‐metal ions into lead‐free double perovskite has garnered considerable attention for improving lattice environment and enhancing photoluminescence (PL) to achieve white light emission. Here, Sb/X (Mn, Er, Ho) co‐doped Cs 2 NaInCl 6 (CNIC) microcrystals (MCs) synthesized by conventional hydrothermal method are developed single‐component emission with various photoinduced transition mechanisms. Sb doping in CNIC MCs causes breaking non‐parity forbidden under 360 nm laser excitation results blue emission; co‐doping successfully broadens spectrum multi‐peak emission, which consists unique X‐peak peaked at 445 nm. The energy transfer channels from both free excitons state self‐trapping (STEs) [SbCl ] 3− X ion proved studied use steady‐state time‐resolved PL spectroscopy. Among them, Sb/Er show dual‐mode 980 excitation. Single‐component emitting diode is fabricated adjusting composition MCs, provides an alternative path realizing illumination.

Fast Visible-Light Photopolymerization in the Presence of Multiwalled Carbon Nanotubes: Toward 3D Printing Conducting Nanocomposites

ACS Macro Letters, Journal Year: 2022, Volume and Issue: 11(3), P. 303 - 309

Published: Feb. 10, 2022

A new photoinitiator system (PIS) based on riboflavin (Rf), triethanolamine, and multiwalled carbon nanobutes (MWCNTs) is presented for visible-light-induced photopolymerization of acrylic monomers. Using this PIS, acrylamide other monomers was quantitative in seconds. The intervention mechanism CNTs the PIS studied deeply, proposing a surface interaction MWCNTs with Rf which favors radical generation initiation step. As result, polyacrylamide/MWCNT hydrogel nanocomposites could be obtained varying amounts showing excellent mechanical, thermal, electrical properties. presence negatively influences swelling properties but significantly improves its mechanical (Young modulus values) electric conductivity. tested 3D printing LCD printer.
