Synergistic extraction of critical metals from the oxalic leachate of spent FCC catalyst

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study introduces an improved hydrometallurgy process utilizing a synergistic approach to improve metal recovery from secondary sources of critical metals. It provides a more efficient alternative to traditional single‐extractant methods for separating critical metals from spent refinery catalysts.

The Effect of Electrolyte pH and Impurities on the Stability of Electrolytic Bicarbonate Conversion

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The performance of bicarbonate electrolysis is largely controlled by the electrolyte inlet pH, the distance between the membrane and electrode, and the impurities present in the electrolyte. By complexing trace metal ions with ethylenediaminetetraacetic acid (EDTA), stability can significantly be improved and longer term operation can be achieved ...

Ni–Zn–Ga Alloy for Weak Sunlight‐Driven Methanol Production From CO2 and H2O at Ambient Pressure

EcoEnergy, EarlyView.
The Ni–Zn–Ga ternary alloy‐assisted photothermal CO2 hydrogenation system coupled with photovoltaic water splitting could convert CO2 and H2O into methanol with a production rate of 709 μmol g−1 h−1 under natural sunlight irradiation. ABSTRACT The sunlight‐driven artificial photosynthesis that converts CO2 and H2O into methanol is a promising approach ...

Raphael seen through MA-XRF: understanding the master and his atelier by studying the Capodimonte collection

Journal of Cultural Heritage
Raphael’s paintings in the Capodimonte collection, ‘Museo e Real Bosco di Capodimonte’ in Naples, offer the opportunity to describe the master’s great career and technical evolution from the earliest production, as in the Baronci Panel , to the mature collaboration with his pupil and successor Giulio Romano for the Madonna of the Cat . At the same time,

Carbon‐Negative Upcycling of Sewage Sludge into Superiorly Stable Gel Via Liquid‐Phase Utilization Strategy for Water‐Remediation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work developed a low‐temperature sludge hydrothermal coupled with gel crosslinking strategy which could upgrade the waste liquid generated from sewage sludge hydrothermal treatment into the hydrothermal‐liquid‐gel. The inventive hydrothermal‐liquid‐gel exhibited the enhanced pollutant removal capability, high synthetic stability, and superior ...

Tuning Cation Disorder in LiNi0.5Mn1.5O4 via Room Temperature Continuous‐Flow Co‐Precipitation and Controlled Heat Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
LiNi0.5Mn1.5O4 (LNMO) precursors were produced at room temperature by Ambient Continuous Turbulent In‐line Mixing (ACTIM) at rates of up to 0.42 kg h−1. The final heat treatment step at 650, 700, or 750 °C, altered cation disorder and the electrochemical behavior of the LNMO cathodes, while the effect of adding MWCNTs to the electrodes, was also ...

Catalytic Pyrolysis of Torrefied Municipal Solid Waste Using Local Iron for Improved Bio‐Oil Yield and Energy Efficiency

Energy Science &Engineering, EarlyView.
Catalytic Pyrolysis of Torrefied Municipal Solid Waste to sustainable bio‐oil. ABSTRACT South Africa faces growing municipal solid waste (MSW) accumulation and energy insecurity due to fossil fuel dependence. Torrefaction improves MSW for waste‐to‐energy use, while conventional pyrolysis produces low‐quality oxygen‐rich bio‐oil.
