Environmental Behavior, Sources, and Effects of Chlorinated Polycyclic Aromatic Hydrocarbons

The Scientific World Journal, 2007
The environmental sources and behaviors of chlorinated 2- to 5-ring polycyclic aromatic hydrocarbons (ClPAHs). ClPAHs are ubiquitous contaminants found in urban air, vehicle exhaust gas, snow, tap water, and sediments.

In Situ Grown Bimetallic (Ni, Fe)12P5 Nanoneedles With Favorable Electronic Structures and Superwetting Surfaces for Highly Efficient and Durable Seawater Splitting at Industrial Current Density

Carbon Energy, EarlyView.
A three‐dimensional bimetallic (Ni, Fe)12P5 nanoneedle array anchored on metal foam with superwetting surfaces and modulated electronic structures is in situ fabricated via a facile one‐step phosphidation strategy (Fe–Ni12P5 NAs@NFF). This material demonstrates exceptional bifunctional activity and long‐term stability at the industrial‐scale current ...

Effect of Transition Metal Powder and Low-Energy Ultrasound Frequency on Degradation Rate of Chlorinated Hydrocarbons in Water

, 2006
水中揮発性有機塩素化合物(テトラクロロエチレン,トリクロロエチレン,四塩化炭素)を超音波洗浄機を用いて分解することを試みた.洗浄機による超音波照射実験では比較的低エネルギーの超音波を用いるため,高温の微小気泡(キャビティ)及びOHラジカルは生成されず,有機塩素化合物の分解は非常に遅いことが確認された.そこで分解反応を促進させるために遷移金属粉末を共存させて超音波照射したところ,分解速度が著しく向上することが分かった.分解速度は ...

Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

Chemistry – A European Journal, EarlyView.
ABSTRACT The development of synthetic procedures for preparing metal nanoparticles with controlled size using sunlight opens new avenues toward more sustainable methods with lower energy consumption. Herein, we propose the use of double‐vacancy halide perovskites as precursors for engineering highly crystalline and small platinum nanoparticles (< 3 nm)

Transport of chlorinated hydrocarbons between sewage and sewer atmosphere

, 1996
Sewage containing volatile contaminants is a potential VOC-source in cities. Thus we tried to evaluate volatilization out of the sewerage system by measurements of contaminants in sewer gas and sewage.
