Improvement of Municipal Solid Waste Syngas Premixed Flame with Cellular Structure on a Flat Burner

Energies, 2023
This research was conducted to study the flame instability of syngas derived from raw municipal solid waste (MSW) and its potential as a natural gas (NG) replacement in power generation. MSW syngas is a mixture of various components such as methane (CH4),

Integrating Direct Air Capture Technology and Plasma Based Calcination for Sustainable Syngas and Concrete – An Experimental Investigation

Advanced Materials Interfaces, EarlyView.
This study presents an experimental Proof‐of‐Concept of an electrified CO2${\rm CO}_2$ loop that combines DAC and GA‐plasma conversion. Atmospheric CO2${\rm CO}_2$ is captured and solidified as CaCO3${\rm CaCO}_3$, followed by plasma‐based calcination to regenerate CaO and with the possibility to split CO2${\rm CO}_2$ into CO for syngas synthesis. This

Liquid Bismuth Catalyst Enables High‐CO‐Selectivity in CO2 Hydrogenation

Advanced Science, EarlyView.
This work introduces a dynamic liquid bismuth catalyst for efficient CO2‐to‐syngas conversion. Stabilized molten Bi nanodroplets on a defective VOx support enable a reversible Bi3+/Bi0 redox cycle at moderate temperatures. Mechanistic insights reveal that Ni‐Bi dual sites synergistically activate H2 and cleave CO2, leading to high CO selectivity ...

Insights Into CO2 Loss, pH Effects, and Tafel Kinetics in Ni Single Atom‐Driven Bicarbonate Electroreduction

Advanced Science, EarlyView.
Selective CO formation in bicarbonate electrolysis is achieved by retaining reactive CO2 and tuning pH, while the competing hydrogen evolution reaction occurs at the interface. The rate‐determining step couples the chemical equilibrium of bicarbonate/CO2 with electrochemical charge transfer, offering insight into optimizing reaction conditions for ...
