Solvent-free hydrodeoxygenation (HDO) of bio-lipids into renewable alkanes by non-precious Ni metal catalysts usually required harsh reaction conditions of, for example, over 360 degrees C. Herein, we reported a NiW bimetallic catalyst that reached a 100 % HDO efficiency over oleic acid under a mild condition of 320 degrees C. This was due to a cat...
The triadic composite of ZnO/CdO heterojunction decorated with reduced graphene oxide (rGO) was prepared using a one-step hydrothermal method. The characterizations of morphology, structure and composition to the composite were undertaken by XRD, Raman, SEM, TEM, XPS, UV-vis spectra. The sensing experimental data indicate that the highest response ...
Emerging electrochemical systems, such as advanced electro-oxidation, provide a potentially powerful alternative to conventional oxidation processes which can often be unsuitable for small, remote and decentralised system applications. The one electro-oxidation process, which may be well suited for these applications, is the use of high oxygen over...
In this paper, we critically review the current state-of-the-art for sensor network applications and approaches that have developed in response to the recent rise of low-cost technologies. We specifically focus on water-related low-cost sensor networks, and conceptualize them as socio-technical systems that can address resource management challenge...
Aiming at SO2 and NOx in industrial flue gas, the simultaneous removal of SO2 and NOx was conducted using red mud as absorbent with O-3 oxidation. The effects of different factors on the desulfurization and denitration efficiency were investigated. The results show that the increase of oxidation temperature is not conducive to the absorption of NOx...

Granular activated carbon (GAC) is used in drinking water treatment plants worldwide to remove micro-pollutants such as pesticides. Early breakthrough of problematic micro-pollutants leads to frequent and costly thermal regeneration off-site. A potential alternative approach is to chemically regenerate GAC on-site (possibly in situ) with an appropr...
Constructed wetlands have been shown to consistently remove a wide range of pollutants from contaminated water. However, no wide-ranging studies exist on the economic viability of this technology. This paper performs a high-level economic comparison between wetland remediation and conventional water remediation technologies, for a wide range of con...
Herein, a novel method for the adsorption of metal ions from sewage by NaP zeolite adsorbent synthesized from stage-treated coal fly ash (CFA) was proposed. The pre-treatment of CFA and grading extraction of silicon and aluminum were explored, and the effects of crystallization parameters and sodium salts on the yield and purity of NaP zeolites wer...
