Integrating agro‐residue valorization and clean hydrogen production: coconut fiber‐based catalysts for NaBH4 hydrolysis

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract A novel phosphoric acid‐treated green coconut fiber (GCF‐C) was developed as a catalyst for hydrogen production from the hydrolysis of sodium borohydride (NaBH4). Characterization techniques confirmed structural modifications, including X‐ray diffraction, scanning electron microscopy, X‐ray fluorescence, Fourier transform infrared, and ...

Decomposition mechanisms in metal borohydrides and their ammoniates

open access: yes, 2017
Ammoniation in metal borohydrides (MBs) with the form $\mathcal{M}$(BH$_4$)$_x$ has been shown to lower their decomposition temperatures with $\mathcal{M}$ of low electronegativity ($\chi_p \lesssim 1.6$), but raise it for high-$\chi_p$ MBs ($\chi_p ...

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...
