GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction

Advanced Functional Materials, EarlyView.
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...

ACID HYDROLYSIS OF OXYCELLULOSE

Sen'i Gakkaishi, 1989
NBSP (P-sample), NaIO4 oxidized cellulose (A-sample) and NaIO4-NaCIO2 oxidized cellulose (C-sample) were hydrolyzed by sulfuric acid in heterogeneous and homogeneous systems.Crystallinity Index (CI) was found to be in the order of P>C>A sample and these of the oxidized samples extremely decreased after hydrolysis.
