已经研究了氢同位素气体与氧化锆或二氧化硅负载的金属纳米复合材料相互作用所产生的异常热效应。在室温下观察到的吸收和放热并没有太大而无法用某些化学过程来解释。在 200–300°C 的高温下,大多数采用二元金属纳米复合材料的样品会产生 3–24W 的过剩功率,可持续长达数周。不仅在D-Pd·Ni体系中观察到了过剩功率,而且在H单键Pd·Ni体系和H单键Cu·Ni体系中也观察到了过剩功率,而单元素纳米颗粒样品没有产生过剩功率。 Pd/Ni比是提高过剩功率的关键之一。最大相平均余热能超过270 keV/D,积分余热能达到100 MJ/mol-M或90 MJ/mol-H。不可能将多余的热能归因于任何化学反应;这可能是由于无辐射核过程造成的。
Anomalous heat effect by interaction of hydrogen isotope gas and metal nanocomposites supported by zirconia or by silica has been examined. Observed absorption and heat evolution at RT were not too large to be explained by some chemical processes. At elevated temperatures of 200–300 °C, most samples with binary metal nanocomposites produced excess power of 3–24 W lasting for up to several weeks. The excess power was observed not only in the D-Pd·Ni system but also in the Hsingle bondPd·Ni system and Hsingle bondCu·Ni system, while single-element nanoparticle samples produced no excess power. The Pd/Ni ratio is one of the keys to increase the excess power. The maximum phase-averaged excess heat energy exceeded 270 keV/D, and the integrated excess heat energy reached 100 MJ/mol-M or 90 MJ/mol-H. It is impossible to attribute the excess heat energy to any chemical reaction; it is possibly due to radiation-free nuclear process.
