Methane sensing at room temperature using photothermal cantilever deflection spectroscopy [J]. Sensors and Actuators B-Chemical, 2015, 221: 564-569. [23] Ifat J, Ehtesham B Q, Goutam K. Unique detection of organic vapors below their auto-ignition temperature using III-V Nitride based triangular...
Methane is activated at room temperature and atmospheric pressure on TiO 2 , supported molybdena catalyst excited by band gap illumination. With pure TiO 2 , complete oxidation to CO 2 is observed in the presence of oxygen. The deposition of 4% molybdena has a pronounced effect on methane ac...
No need for a metal: A combination of mass spectrometry and computational studies (density functional theory and coupled-cluster methods) shows that [P4O10].+ is the first polynuclear nonmetal oxide cation that is capable of activating the CH bond of methane at room temperature (see picture)....
High pressure behaviours of solid methane were examined in a pressure range of 0.5 GPa to 86 GPa at room temperature using diamond anvil cell. In-situ X-ray diffractometry and Raman spectroscopy revealed existence of two high pressure phases above 35 GPa. The Raman spectra showed clear peak spl...
Just one step: Reactivity studies demonstrate that in the gas phase [Al2O3].+ clusters can efficiently conduct the direct conversion of CH4 into CH2O at room temperature (see scheme). The reaction mechanism is highly complex involving oxygen‐atom transfer and a double hydrogen‐atom transfer.关...
Nevertheless, the state of natural gas, especially methane, at room temperature and atmospheric pressures is gaseous. Therefore, it is transported using gas pipelines or LNG systems. Small and medium-sized natural gas fields have difficulty using such methods. Therefore, efficient conversion of ...
little is known aboutthe correlation among the state of M–O•,its reactivity for CH4, and the nature of the zeolite environment.Here, we report a combined spectroscopic and computational study ofthe room-temperature activation of CH4 over ZnII–O• in the MFI zeolite. One ZnII–O• ...
The dynamic thermal process for methane sorption in coal has not been quantitatively studied, and the temperature change induced by the heat of adsorption on the sorption equilibrium state has not been confirmed by tests. In order to probe the temperature evolvement and its effect on methane adsor...
A key benefit of using molten Ga catalyst is the enhanced methane absorption in Ga at lower temperatures; this leads to a surprisingly low apparent reaction barrier of ~0.16eV below 300°C. The faster growth kinetics due to a low reaction barrier and a demonstrated low-temperature graphene ...
(Alliance Instruments, Frepillon, France). Fresh soil samples were weighed and then dried in an oven at 105 °C to a constant weight to determine gravimetric soil moisture94. The other parts were air-dried and stored at room temperature (25 °C). Air-died soils were used to determine ...
