Hydrogen and carbon monoxide are reacted under conditions sufficient to form methanol. The molar ratio of hydrogen to carbon monoxide is at least two moles of hydrogen to one mole of carbon monoxide and the overall molar ratio between methane, water and carbon dioxide is about 3:2:1. Methane...
In recent years, methane has become increasingly abundant due to the development of shale gas fields and other cost efficient or renewable feedstocks such as biogas. Methane is also considered as one of the greenhouse gases with a global warming potential 50 times higher than carbon dioxide1. Met...
The world needs a deal duringCOP28to limit a nasty source of emission 温室气体 各国需在COP28大会期间达成协议以规范令人厌恶的排放源 METHANE IS A potent greenhouse gas. Over 20 years it has over 80 times the planet-cooking power of carbon dioxide, and is the culprit behind nearly 45% of w...
A series of A‐modified hexaaluminates, ANiAl11O19-δ (A = Ca, Sr, Ba and La) as new catalysts for carbon dioxide reforming of methane to synthesis gas, were prepared by decompositionof nitrates and calcination at high temperature. Nickel ions as active component were inlayed in...
Seagrass ecosystems are important carbon dioxide sinks that can sequester carbon for centuries as organic matter in sediment. They are also a major source of methane, a potent greenhouse gas, which limits their carbon sink capacity. However, data are lac
Carbon dioxide reforming of methane to synthesis gas has been investigated over supported Ni catalysts in the temperature range of 500–850°C. Addition of CaO (10mol%) promoter to the Ni/γ-Al2O3 resulted in an increase of reaction rate and an improvement of catalyst stability, which may ...
INCREASING concern about world dependence on petroleum oil has generated interest in the more efficient use of natural gas1–4. The conversion of methane to the common feedstock synthesis gas (carbon monoxide and hydrogen) by steam reforming is already w

The device is a sort of solar panel studded with nanoparticles of copper and iron. It can use the sun's energy or an electrical current to break down the carbon dioxide and water. The base layer is a silicon wafer, topped with nanowires, each 300 nanometers tall and about 30 nanometers...
Table 2. Some catalysts for the heterogeneous electrocatalysis of carbon dioxide to methane. 4.1. Catalyst-Structure Engineering In heterogeneous catalysis, the catalyst’s structure impacts the product distribution of electrocatalyzed CO2 [98,99,100,101]. This section focuses on summarizing the differen...
