Synergistic effect of [email protected][email protected]2 nanowire heterostructures for high-performance asymmetry supercapacitor with long cycle life

AbstractHeterostructures show excellent performance in energy and environment fields due to the unique interface structure and synergistic effect of multi-components. Here, we introduce a stepwise method to prepare multi-element [email protected][email protected]2 heterostructures on nickel foam as binder-free supercapacitor electrode material, where crystalline Co3O4 acts as intimal “core” and wrinkled ultrathin MnO2 nanosheets as the outer “shell”. In three-electrode mode, [email protected][email protected]2 shows excellent electrochemical performance with a high cyclic specific capacitance of 1335.3 F g−1 at a current density of 20 A g−1. Furthermore, the asymmetry supercapacitor device assembled with [email protected][email protected]2 heterostructures and active carbon exhibits high specific capacity (126.6 F g−1 at a current density of 0.5 A g−1) and long life (about 61 F g−1 at a relatively high current of 20 A g−1 after 40,000 cycles). Compared with [email protected] or [email protected]2, the improved performance of [email protected][email protected]2 heterostructures is proposed to be attributed to the synergistic effect in multi-components. Remarkably, the introduction of C between Co3O4 and MnO2 could promote the electron transfer, reduce the impedance and thus improve the electrochemical performance of the heterostructures.

Full Length ArticleInvestigation of ammonia removal from the simulated producer gas of biomass gasification by H2-reduced titanomagnetite

Highlights•H2-reduced titanomagnetite is superior to unprocessed titanomagnetite to decompose NH3 in Ar gas.•Temperature has significant effect on removal of NH3 in simulated producer gas by the reduced titanomagnetite.•Side reactions have been identified during the NH3 decomposition in the simulated producer gas.•Carbon deposition deactivates the reduced titanomagnetite for NH3 removal at 500 °C.

Geotourism, geoconservation, and geodiversity along the belt and road: A case study of Dunhuang UNESCO Global Geopark in China

AbstractDunhuang UNESCO Global Geopark (DHGG) is rich in geoheritage and contains scientific value for studying the sedimentation environments and paleoclimates of Western China. The Geopark is also notable for its aesthetic, cultural, artistic, and recreational value for tourism development. Since geographer Sven Hedin’s discovery of a yardang landform around Lop Nur in 1903, the area has been heavily studied. After the site was designated a National Geopark, geoconservation and geotourism began to rapidly develop and problems associated with these changes emerged. This study characterizes some of DHGG’s typical geoheritage, existing geoconservation, launched geotourism, and also describes some of the area’s challenges. In addition, the opportunities and challenges of DHGG arising from the construction of the Silk Road Economic Belt and 21st-Century Maritime Silk Road (B&R) are discussed. To benefit the sustainable development of DHGG, it is prudent to continue promoting geodiversity, geoconservation, and geotourism by making use of the advantages brought by the B&R.

Involvement of glucose in the regulation of ethylene biosynthesis and sensitivity in cut Paeonia suffruticosa flowers

Highlights•Glucose delays senescence and extends vase life of cut P. suffruticosa flowers.•Glucose inhibits climacteric ethylene production of cut P. suffruticosa flowers.•Glucose impairs ethylene biosynthetic activities by repressing PsACS1 expression.•Glucose reduces the sensitivity of cut P. suffruticosa flowers to ethylene.

One-pot synthesis visible-light-active TiO2 photocatalysts at low temperature by peroxotitanium complex

Highlights•One-step synthesis of TiO2 with different anatase/rutile ratios at low temperature.•Peroxotitanium complex has attracted much attention to prepare more active TiO2.•Carbonate-like species formed in situ and enhanced visible light absorption.•Enhanced the visible light photocatalytic activity for degradation of RhB and OII.•The proposed approach is greatly energy-efficient and environmentally benign.

Research paperInvestigation of hydrogen sulphide removal from simulated producer gas of biomass gasification by titanomagnetite

Highlights•Unprocessed titanomagnetite is superior to reduced titanomagnetite for removal of H2S from simulated producer gas.•The most effective operation temperatures for H2S removal by the unprocessed titanomagnetite are from 400 to 450 °C.•Presence of water vapour and CO in the producer gas has adverse impact on the H2S removal.•Steam and carbon formation significantly reduces the titanomagnetite activity for H2S conversion.
