Electrochemical Formation of BiVO4/BiPO4 Photoanodes for Enhanced Selectivity toward H2O2 Generation

open access: yesAdvanced Functional Materials, EarlyView.
In acidic KPi, V dissolves from the BiVO4 lattice, while adsorbed phosphate reacts with the electrode under an external bias, forming a BiPO4 surface layer. This BiPO4 layer exhibits stronger bicarbonate adsorption, redirecting the water oxidation pathway toward two‐electron H2O2 production.

An In Situ Study of the Topochemical Transformation of Hybrid Layered Hydroxides Into Metallic Nanocomposites

open access: yesAdvanced Functional Materials, EarlyView.
Herein, the topochemical transformation of cobalt‐based layered hydroxides into nanocomposites is investigated using advanced real‐time characterization techniques combined with thermogravimetric analysis. The study reveals how interlayer carboxylic acids direct the transformation pathway, highlighting the role of carbon content and anion length. These

Heterogeneities in carbon fibers

Carbon, 1975
Abstract Acrylic fibers, stabilized acrylic fibers, and graphite fibers have been selectively etched by ion bombardment. After ion etching, the fibers are characterized by structures oriented transverse to the fiber axis with an average spacing ranging from 500 to 3000 A.

Wettability of a Single Carbon Fiber

Langmuir, 2016
A new method was developed to measure the dynamic contact angles of a single carbon fiber at low and high velocities, taking into consideration both the intrinsic variability of the carbon fiber diameter and the extremely small amplitude of the capillary forces. The effectiveness of the method was strengthened by fitting the experimental contact angle ...
